The world's largest island group
The world's largest island group is composed of more than 13,000 islands and the Philippines, which are called Malay Islands. The main islands have the big house of Indonesia, Xiaoyu Islands, Muka, Irian, Philippines, Ladong, Milua, Miran, and Islands. The islands also include East Malaysia, Brunei, Papua New Guinea. The islands are located between the Pacific Ocean and the Indian Ocean, extending 6100 kilometers along the equator, the largest width of the north and south, with a total area of about 2.43 million square kilometers. West and Asian continents have a Torres Strait between the Bss Strait between the Malacca Channel and Nanhai, North and Taiwan. In addition to the northern part of the Philippines, the islands are within 10 degrees of equator, with average temperature 21 ° C, annual rainfall from 8100 mm to 500 mm, and most of the region exceeds 2000 mm. Every year from January to November, the Southwest Pacific has generated more than 20 times, often attacking the Philippines. The animal and plant groups in Malan Islands are very rich and vary. The rural and agricultural economy accounted for the overpage advantage, the vast majority of rural residents are settlers, main crops are rice, and commercial crops include rubber, tobacco, sugar, etc. Forest resources are important, providing valuables, resins, rattles, etc. Petroleum is the main mineral, tin production accounts for 10% of the world's output. Hydraulic resources are abundant, but not fully developed, the manufacturing industry is not developed, the light industry is mainly textile, paper, glass, soap, cigarette, etc.
The world's thicker South American Ecuador's Qinbolaçona. From the top-to-ceramics to the peak peaks of 6384.1 km. Chin Boracus is located at the Andes of Sikdilla, Hill, 6.310 meters above sea level, is the highest peak of Ecuador. It has been mistaken for a long time to be the highest peak of the Andean. It is a sleeping volcano, there are many cars, mountains and glaciers, over 4,694 meters, and the snow is snowing. The British Mountaineering Athlete E-Wales on the 1880 Mount Wales on the peak. Here is the plateau region in the middle of Ecuador, mainly with agriculture and animal husbandry, mainly with sheep, cows, cereals, potatoes, fruits and fiber plants. (Far, Qin Boracus)
The world's highest plateau Qinghai-Tibet Plateau is China's largest plateau, and it is also the highest in the world, so there is a "world row". The Qinghai-Tibet Plateau is 2.4 million square kilometers, most of the altitude of more than 3,500 meters, including all in Tibet and Qinghai, part of Sichuan, south of Xinjiang, and Yunnan. The mountain around the plateau is surrounded by Hamalayas, the north has Alkam, Kunlun Mountain and Qilian Mountain, and the West is Karakun Mountain, east is the transverse mountain range. There are also Tang Gu Lushan, Okodus Mountain, and Tang Gu Lushan, etc. Most of these mountains have more than 5,500 meters, including 16 mountain peaks over 8,000 meters in Himalayas. The plateau is separated by mountains into many basins, wide valley. There are many lakes, Qinghai Lake, Nami, etc. are all inland salty water lakes, prosperous, boron sand, and malaid. The plateau is the birthplace of many large rivers in Asia, such as the Yangtze River, the Yellow River, the Yulongjiang, Nujiang, and Yarun Zangbu, etc., there is a rich hydraulic resources. Due to the high terrain, most of the heat is insufficient, the hottest temperature of the most hot month is less than 10 degrees Celsius, no absolute frost, and the grain is difficult to mature, and should only graze. The animal's animal is dominated by a cold yak, Tibetan sheep, and goats. River valles below 4,200 meters can grow crops, mainly cold-resistant varieties such as green, wheat, pea, potatoes, rapeseed. The Yarung Zangbu River Valley is low, there is no cold in winter, and wheat can safely. There are many hydropower stations, coal mines, steel mills, chemical plants, woolen mills, and paper mills. At present, there are 4 roads such as Sichuan Tibet, Qingzang, Yunnang, and New Tibet. Civil Aviation Express Tong Xining, Golmud, Lhasa. (Satellite shot of the Qinghai-Tibet Plateau)
Most of the world's largest desert North African plateau is called the Sahara desert, but the real sand is only one-fifth of all of the area. In addition to the desert, there are grant and stone desert. These three terrain are inlaid. The Sahara desert almost includes the entire North Africa, west of the Atlantic, north of the Atlas Mountains and Mediterranean, East and Red Sea, Nankian Saheler (Saheler is a semi-desert hayland transition zone, full thorns and shrubs) . Western Sahara, Morocco, Algeria, Tunisia, Libya, Egypt, Mauritania, Mali, Niger, Chad and Sudan and other 11 countries are distributed in this area. The terrain characteristics here is: seasonal flooding shallows and large oasis low; vast multi-stone plains; plateau filled with rocks; steep mountains, sand dunes and Shashi. The soil is generally less organic substance, not suitable for biological growth, and the soil of the depression often contains salt. It has become a climate desert in about 5 million years ago. Thereafter, sometimes dry, sometimes moist. At present, the desert is mainly divided into two climate zones. The northern part is a dry subtropical climate, and the seasonal climate change and the temperature difference of daily have a great temperature difference. Precipitation is mainly concentrated in winter, but in some dry areas, the summer is common floods in summer. Spring often has hot air from the south, with sand. The southern part is a dry tropical climate, and there is often a sand in the northeast in winter. There is no one in the vast area of Sahara, only someone in the oasis is settled. Plants are mainly a variety of herbaceous plants; coconut dates; 柽 属 属 and hgyphohuma It is rich here, oil, groundwater, but due to traffic inconvenience to development. (This is the satellite picture in the eastern part of the Sahara desert. The left deep blue part is the Atlantic Ocean. The world's largest foreign Pacific Nanyire, north to Arctic, west to Asia and Australia, East Town South, North America. One-third of the earth is about one-third of the world is the largest ocean in the world. The area does not include neighboring seas, about 1,655,250,000 square kilometers. It is 2 times that of the second ocean atlantic area, and more than 2 times the water capacity. The area exceeds the sum of earth land area including Antarctica. The average depth (excluding the sea) 4280 meters. There are many sea in the West Pacific, from the north to the south of Bailing Sea, Okhtzkhai, Japanese sea, Yellow Sea, East China Sea and South China Sea. The Yellow River, the Yangtze River, the Pearl River and the Mekong River were injected into the Pacific Ocean. The western bottom of the Western East is gentle. Western Pacific's water is more than 600 meters above the sea in some places. From the northwestern Pacific Ocean, there is an extension to the south to Qiandao, Xiaoyanyuan, Mariana, Yipu and Palau; Self Palau extends to Bismarck, Solomon and Santa Cruz; finally by Samoa Islands , Kmadk, Chatham and Macquarrie. Since the proportion of northern land and oceans is higher in the south, and the influence of NAV terrestrial ice sheets, the water temperature in the North Pacific is higher than the South Pacific. The salt containing salt in the equatorial and wind-free sea water is lower than the faith. The maximum impact on the vertical sevily in the Pacific is the cold water generated around the Antarctic continent. The waters of the polarity is sinking, and then spread to the north to make a large bottom layer of the Pacific Ocean. Deep cold water in the Western Pacific, in the near Nairi near NAP, Japan. The mainstream tributary of the deep sea is from eastward in the east and then flows to the polar. The Influence of the Deep Sea Circle Since the Sink of the Summer Sea Surface in the Digital Flow Conference. In the Pacific Tropical Convergence Region, between the north and south latitude 35o to 40o, the larger the depth of the equator, the larger the depth of the sea, the most important convergence zone is between 55O to 60o in the South.

The world's biggest drop of waterfall Anhel Waterfall, also known as the Churn Meru Waterfall. Located in the Venezuela Bolivar, the Carloni River triggered the Qilun River. The waterfall dropped 979 meters and the bottom is 150 meters. The waterfall is straight from the Pingding Plateau Oust Pu Yishan, almost never touching the steep cliff. In 1935, the US explorer Angel found this waterfall, and Her Her took the plane to crash near the waterfall, in order to commemorate him, the Venezuelan government named the waterfall with Angel.
The world's largest river area is the largest river in the world. The Amazon River flowing through the Amazon Plains in the world is the largest plains in the world, the world's largest traffic, the most wide range of rivers. Its length is second only to the Nile (about 6400 km), for the second largest river in the world. It is estimated that there is approximately 20- 25% of water flowing on the Earth surface in the Amazon River. The estuary is 240 kilometers wide. The flooler flow rate is 180,000 cubic meters per second is 10 times the Mississippi River. The amount of laxative is so large, making the sea within 160 kilometers of the shore. It is known to have more than 1,000 tributaries, of which 7 have more than 1600 kilometers. The fertile sludge under the deposited of the Amazon river nourish 65,000 square kilometers, and its watershed is about 7.05 million square kilometers, which is almost twice that of any other big river basin in the world. The famous Amazon tropical rainforest is growing in the Amazon River Basin. Here is the largest plains in the world (the area is 5.6 million square kilometers). The plain is low. Most of the following 150 meters above sea level, so the river is fluid, and there are many lakes. Rain, humidity and continuous high temperature are significant climate characteristics. Here is the world's most abundant and diverse biological resources, and various creatures have millions. The highest water temperature in the world is located between the Northeast of Africa and the Arabian Peninsula, the shape is narrow, from northwest to the southeast, with a maximum width 306 km, with an area of 450,000 square kilometers. The Red Sea North Term is brought into two small bays, the West is Suei Bay, and is connected to the Mediterranean Sea through the Suez Canal through the Suez. According to the theory of seabed expansion and sector construction, the Red Sea and Aden Bay are the prototype of the ocean. According to research, the red sea is a marine-based rock, and there is also a long crack of the horizontal disorder of the ocean ridge in the seabed shaft, and is connected to the rupture belt. The African continent starts from the Arabian Peninsula in the new world in 21 million years, and is still expanding at a speed of 1 cm per year. The steep wall on both sides of the Red Sea is standing, the coral reef in the shore, and there are fewer ports. The average depth of the entire Red Sea is 558 meters and the maximum depth is 2514 meters. The Red Sea is covered with the tropical desert on both sides of the east, and the air is hot, the dust is filled, and the dust is less than the day. Less precipitation, the amount of evaporation is very high, one of the world's water temperature and the highest salin. August 70 to 32 degrees Celsius in August. (Satellite picture in the Red Sea)
The world's most light sea Barobi is the inner sea in the north of the European continent. Town in Northeast - Southwest. More than 420,000 square kilometers. Generally, water is 40 to 100 meters, and the deepest is 470 meters. The salinity of the general sea water is about 34 to 30,000. The Baltic Sea Water Salm Salinity is from 8 to 10,000 in the western part, drops to 2,000,000 percent of the middle of the middle and 2,000 percent of the eastern part. It is the lowest salt in the world. Baltic island, coastline, multi-port. There are 250 rivers injected. It is an important sea transportation channel in Nordic. The northern and eastern seals reached 3 to 4 months, and the south is usually not blot. The important sea port along the coast has St. Petersburg, Helsinki, Stockholm, Copenhagen, etc. (Satellite picture)
The world's largest freshwater lake, Lake Subilia, North America, the top northwest and biggest one in North America. It is the world's largest freshwater lake, and the world is second only to the second largest lake in the sea (Qihai is a salt lake). The northeast of the lake is Canada, the southwest is the United States. The lake is 616 kilometers long, the widest place in the north and the south, the lake is 180 meters above sea level, the water area is 82103 square kilometers, the maximum depth is 405 meters. The amount of water storage is 12,000 yuan. There are nearly 200 rivers into the lake, with the largest in the Nikong and the St. Louis River. The main islands in the lake include Royel Island (US National Park), Apostel Islands, Mickey Pinkten and St. Ignas. Along the lakes, the scenery is beautiful, and the population is scarce. The water quality in Subilia is clear, and there are many winds and waves in the lake. Seasonal fishing and tourism are the main projects in the local entertainment industry. There are a variety of minerals. There are a lot of natural harbor and artificial ports. The main ports include Canada's Sandbe and Tacott, USA. The annual navigation period is 8 months. The lake found that the French explorer found that the lake was taken from French, meaning "Shanghu". (Satellite Picture) The world's highest peak, Everest is the main peak of Himalayas, the world's highest mountain, 8848.13 meters above sea level. It is located in the middle of the hi Marraas in the junction of Tibet and Nepal Kingdom. Norta latitude 27 ° 59 '15.85 ", East 86 ° 55'39.51". The mountain is mainly composed of the crystalline rock system. The glacier is large, with more than 600 glaciers, with an area of 1600 square kilometers. It is a modern glacier role center in low latitude regions. The upstream of the sniper is commonly developed with a tall icehouse, which is a special form of the Valley Glacier in the Everest Region. The northern, east and southwest of Eve Mountain have a large ice hood, making the peak of 3,000 meters from the bottom of the ice hood. In the North slope of Everest, 7450 meters above sea level is the junction of ice and rock, and the ice is snowy, the upper part is steep, the wind is strong, the snow is unable to accumulate and the rock is bare. The peak is often covered with clouds. It seems like Everest for the flag of the flag. This is the unique meteorological phenomenon of Everest, and it is called the flag cloud. In 1718, the Qing Dynasty was labeled as Zhu Male Maolin. In 1855, the British named Evoras Peak. In 1952, my country's government was renamed Zhu Mount. On May 29, 1953, the British two expedition members were successfully summit from the South slope of Nepal. On May 25, 1960, China's mountaineering team was successfully successfully summit from North slope. On May 27, 1975, China's mountaineering team once again successfully closed, and got a standard in the top of the main peak, the first time I got a high degree of accurate data from Mount Everest. In May 1988, China, Japan and Nepalese athletes achieved a feat of the top of the Everest from the south and North slopes. In 1989, the state established a Natural Reserve of Everest and an area of 3,000 square kilometers. (Yuanliang peak)
The world's highest dead volcano is a Avoida, located in Argentina, with an altitude of 6959 meters, which is recognized as the highest peak of the West Hemisphere. The peak is located in the northern part of the Andes, the peaks are in the northwestern sectors of Argentina, but their wings extend to the lowland of Chilean San Diego.
The world's largest coral reef Coral Sea is located in the southwestern part of the Pacific, Australia and New Guinea East, New Caledon and New Herbry, West, south of Solomon Islands. Northern and south is about 2250 kilometers, there are about 2410 kilometers wide and 4,791,000 square kilometers. The north of the South latitude 20o is mainly the seabed plateau of the Coral Sea, and the plateau is a coral sea. The South Solomon Hugou is 7,316 meters deep, and the new Herbury is 7662 meters deep. The Coral Sea is named in a large number of coral reefs, which is the most famous in the Great Barrier Reef. The Great Barrier reef extends along the Side of Australia, near 2,000 kilometers, with a total area of 210,000 square kilometers, is the largest coral reef in the world.
The world's widest waterfall Iguazu Falls are located in the 23 km from the Iguo River and the Balaun's convergence point in Argentina and Brazil. The waterfall is a horseshoe, 82 meters high, a width of 4 thousand meters wide, and is 4 times the width of Niagara Falls in North America, which is wider than the Victorian Waterfall in Africa. There are many trees that have many trees in the edge of the cliff, making the Iguazu River to divide 275 femoral or diarrhea, heights 60 to 82 meters. In the rainy season of November to March, the maximum flow rate of the waterfall can reach 12750 cubic meters per second, with an annual average flow of 1756 cubic meters per second. The wide river of the Iguazu River, falling into a narrow canyon from the edge of the Parana plateau, forming this waterfall, people describe it as "the sea to diarrhea in the abyss". The water splash is liter, rises from the bottom of the waterfall to the air, and the water mist is nearly 150 meters, and it is spectacular. In 1541 Spanish explorer Baka first discovered the waterfall, now, Argentina and Brazil are also in the waterfall near the waterfall in the waterfall in the waterfall in Argentina and Brazil. The world's annual precipitation is the largest area of Hawaii, is a group of volcanic island in the middle of the Pacific, a state in the United States. It consists of 8 lotions and 124 areles. Hawaii is the transportation and cultural center of the Pacific Waters, known as the "Three intersections of the Pacific", and it is still an important tourist attraction. The capital of Honolulu (Honolulu) is located in Wahahu. The largest Magnificent volcanic eruption in the area of Hawaii. Hawaii is located at a slight position in the northern return line. Because the favy has blown over the Pacific Ocean, the vast water plans to stabilize the climate, and its gentle tropical climate is considered to be the most ideal place in the world. The rainfall between the places here is different. Wai Yulaia Allah, Koai Island is known as the world's most rainy area, and has recorded an average rainfall in the middle age of 11280 mm. The average annual precipitation on the Average annual water on the island of Hawaii is only 220 mm. Due to the wet air brought by the hammer, the water in the air is very easy to condense, forming an umbrella cloud, fluttering along the wind coast and mountains, the vegetation in these areas is more than the vegetation in the wind coast.

The largest area of the world's wind is not only the coldest place in the world, but also the world's largest region. There is 300 days, with average 8 or more years, the annual average wind speed is 19.4 m / sec. The maximum wind speed observed by M M Minson in 1972 was 82 meters per second. The French Dilville station observed the wind speed of 100 meters / sec, which is equivalent to three times the 12-level typhoon, which is the largest wind speed recorded in the world. The Antarctic storm is so powerful because the San Polar's snow surface temperature is low, and the nearby air is quickly cooled to shrink and the density is increased. The ice cover covering the Antarctic continent is like a central thick, surrounded "discus", forming a steep slope terrain between a central plateau and coastal region. The refreshing cold air declines sharply from the inland height, to the coastal zone, due to sudden falling, so that the speed of the cold air flow is increased, so that strong, high speed is extremely fast. The Antarctic has no four seasons, only warm and cold season. Warm seasons from November to March; the cold season from April to October. In the warm season, the average temperature in the coastal area exceeds zero degrees, the average temperature in the inland area is zero 20 to zero 35 degrees Celsius; when the cold season, the coastal zone is 40 to zero 30 degrees Celsius, the inland area is zero 40 to zero 70 Celsius. At the beginning of 1967, Norway was measured nearly 94.5 degrees Celsius at a pole near the pole. It is estimated that there may be a low temperature of 95 to zero 100 degrees Celsius on the southeast Audio.
The world's largest wind and waves is the rocky sea otter in the southern end of the Cape Peninsula in the southwest of Cape Town. It is highly storm that the wavy is raining, and the waves are located in the warm Mozambique of the Indian Ocean and the coincidence of the Cold Bentger Diagonal flow from the Antarctic Waters. In 1939, it became a nature reserve.
The lowest point in the earth's surface is the lowest spot in the dead sea. The water there is about 400 meters from the sea level. The Dead Sea is an inland salt lake, located in Israel and Jordan, Jordan Valley. The West Coast is the Jewish Mountain, the East Coast is an Jordan Plateau. The Jordan River is injected from north. 80 kilometers long, the wide range is 18 kilometers, with a surface area of about 1020 square kilometers, and the deepest is 400 meters. The Dead Sea is located in Jordan - the lowest part of the dead sea, is the northern continuation of the northern part of the East Africa. This is a sinking crust, clip between two parallel geological fault cliffs. The Dead Sea is located in the desert, which is very small and irregular. The annual rainfall of the Lisasan half is 65 mm. Winter climate, hot summer hot. The amount of evaporation of the lake is 1400 mm, so the lake often forms a concentrate. The water level of the lake has seasonal changes in 30 to 60 cm. The dead sea water is high, and the higher the bottom of the lake. The deepest lake has been granulated (general sea water is 35,000, while the salt containing salt of the Dead Sea is about 230 to 250. The salt in the surface of the surface of the surface is 227 to 275 grams per liter, deep water 327 grams.). Swimmers are extremely easy to float due to high saline concentration. There are no other movable plants in the lake. The fish from the Jordan River or other small rivers will die immediately during the boom. The shore plant is also mainly a salt plant that adapts to salt bases. The dead sea is a lot of salt storage. The dead sea lake is ridiculous, the fixed residents are very small, and the small pieces of cultivated land and nature are met. The longest mountain of the world has about 9,000 kilometers long dependent in Seven countries, almost three times in the Himalayas, and the mountains are majestic and beautiful. It is one of the most spectacular natural landscapes in the world. The Andes is a Codila La Mountain, which has been extended from North America to South America. The whole length is 18,000 kilometers, which is the longest mountain of the world. The Andes has a lot of more than 6,000 meters above sea level, and the peak of snow in the mountains. The Avoida Mountain in the southern mountain range is the highest peak of Andes, with an altitude of 6959 meters. It is also the world's highest dead volcano. Ejiakov volcano is 6723 meters above sea level, which is the world's highest living volcano. South America is multi-volcano, which are mainly distributed in the Andes, here there are more than 40 live volcanoes. The Andes has a large copper mine in the Andes. Here is the world's largest underground copper mine. It is 1200 meters below the surface. (Satellite shooting part)
The world's largest basin Congo basin is located in the middle of Africa, mostly in the Democratic Republic of the Congo, in a small part of the Republic of the Congo. The area is 337 million square kilometers, which is the largest basin in the world. Basin North and South is the plateau, and the eastern part is the large rift, the gap is in the western part, the downstream and estuary. The equator line passes from the middle of the basin. The Congo Basin includes most of the Congo river basin, with an average sea level, with large swamp. The surrounding plateau mountain is more than 1000 meters above sea level. Many of the rivers of the Congolese River are all incorporated into the basin, so the water system is developed. The climate in the basin belongs to the tropical rainforest, the annual average temperature is 25 to 27 degrees Celsius, and the precipitation is 1500 to 2000 mm or more. Here is a lush tropical forest with a variety of precious tree species and tropical crops. The marginal minerals of the basin is rich, and the water resources in the basin are abundant. Therefore, it is said that the Congo Basin is "Zhong Numei".
The longest country of the coastline is referred to as Australia. Located in the southwestern part of Ocean, the Northeast Pacific, West, and South Indian Ocean. Composed of islands such as Australian continent and Tasmania. Australia has a sea, and its coastline is 36,735 kilometers. The area is 7.68 million kilometers. The population is about 17.89 million. Capital Canberra. The Australian landlocked land is mostly low, with an average of 300 meters above sea level, the highest peak of Corsico, 2.228 meters above sea level. 35% of the entire area is desert and half desert. The river is mostly intermittent intrava. Most of the tropical, subtropical climate. (Satellite picture can see the multi-changed coast) The ocean deepest depth Mariana Harogou is located in the North Pacific, Mariana Islands, which extends 2550 kilometers, an average of 69 kilometers wide. There is a small steep valley at the bottom of the main ditch. In 1957, the Soviet Union surveyed the ship was measured by a depth of 10990 meters, and there was a new record of 11034 meters. In 1960, the US Navy was explored from the "Ricster" manufactured by France, and created a record of 10911 meters in ditch. It is generally believed that the ocean plate collides with the mainland plate plate, which is slightly dissolved under the insertion of the continental density, and gradually dissolved under the insertion of the mainland sector. In places where collisions are collisted, the ditch is formed, and the island arc and the coastal mountain are often formed near the continent. These places are a strong area of geological activities, which is characterized by volcanoes and earthquakes. (Computer 3D image at the bottom of the ditch)
The world's longest river Nile river, the Northeast of the Africa, flowing through Burundi, Rwanda, Tanzania, Uganda, Ethiopia, Sudan, Egypt, across the world's largest Sahara desert, and finally injects the Mediterranean. The watershed area is about 3.35 million square kilometers, accounting for one-year-old area of the African continent, 6650 kilometers long, with an average annual flow of 3,100 cubic meters per second, for the world's longest river. The Nile River Basin is divided into seven regions: Dongyu Lake District Plateau, Shanyue River District, Bai Nihe District, Cream Nile District, Atbara River District, Khartoum, Nile District and Nile Delta. The farthest source is the origin of the Cargara River in the Non-Lake District of Burundi. The Hebei flows through Tanzania, Rwanda and Uganda, injected from the West Lake Victoria Lake in Africa. The Nile is from the lake, called Victorian Nile. The river passes through the Lake Albert and Albert, and it is called the Albertni River after flowing out, and the River is called the Batt River. Another source of Central Ethiopian Highlands and the White River in the Sudan of Kasushi, then accepting the last main tributary Atbara River in the north of Damier, called the Nile. The Nile River wrapped in a S-shaped northwest, and injected into the Nazier Reservoir after three waterfalls. After entering the Nile Delta in the Egyptian capital, the river water exported to the Nile Delta, divided into several tributing, and finally injects the eastern end of the Mediterranean. The Nile River has a regular basis. In the north of Sudan, it will start to rise in May, reaching the highest water level in November, and the water level gradually decreases, from 1 to May for low water level. Although the flood is regular, the amount of water and the current tide changes very large. The cause of this phenomenon is that the Qingni River and the Atbara River, the water source of these two rivers from seasonal heavy rains from the Ethiopian plateau. More than 80% of the Nile river is provided by the Ethiopian plateau, and the remaining water comes from the Lake East Aboriginal Lake. When the flood arrives, it will flood both sides of farmland, and the flood will leave a thick river mud, form a fertile soil. Four five thousand years ago, Egyptians knew how to master the law of floods and using both sides of fertile land. For a long time, the Nile River Valley has always been a cotton field, and rice flowers are fragrant. In the Sahara Desert and the left and right in the Arab desert, the winding Nile is like a green profile, full of infinite vitality. (Riverside scenery)
The world's largest inland lake is the world's largest inland lake, located in the vast Central Asia and Southeast of Europe, and the west is a high Caucasus. The entire sea is narrow, the North and the North is about 1200 kilometers, and the average width of things is 320 kilometers. The area is about 386,400 square kilometers, and it is more than doubled than the five fresh water lakes in North America. Richard lake shore line 7000 km long. There are more than 130 rivers into the sea, of which the Volga River, the Ural River and the Jetke River are injected from the north, and the water of the 3 rivers accounts for 88% of the water injected water. Up to 50 islands in the sea, but most of them are small. The sea basis is substantially in the north, middle and south. The shale is a flat deposition plain in the north, with an average depth of 4 to 6 meters. The central part is an irregular sea basis, the walker walked in the western slope, and the water is gentle, and the water is approximately 170 to 788 meters. The southern depression has a deepest 1024 meters, and the average daily water depth is 184 meters, and the water accumulation of lake reaches 76,000 cubic meters. The annual evaporation of the sea is 1000 mm. With a hundred years, the area and depth of the inner sea have changed many times. Luhai provides superior water transport conditions for countries in the coast, and there are many ports along the coast. Some ports are connected to the railway. The train can be driven directly to the boat to the side. (The satellite picture of the sea, the intersection of the white line is Azerbaijan Capital Baku. The upper left corner is the Volga River into the lake.) The world's largest Delta world is the Ganges Delta, which is 320 km wide, starting point from the sea It is 500 kilometers, with an area of more than 70,000 square kilometers, belonging to Bangladesh and India. The flow of the Ganges, there are 8 main waterways, and together with the Buna Bay, they have formed a broad Ganges Delta. In the Delta area, the Ganges is divided into many forks, which is a very characteristic delta. Here, the soil is fertile, agriculture, is an important planting area in South Asian mainland rice, wheat, corn, jute, sugar cane and other crops. There are some large mangroves and swamps in the estuary. It is low here, only 10 meters above sea level. The river network is dense, the coastline is funny, and the storm is not easy to disperse, and it is gathered in the vicinity of the Henghe mouth, forming a strong tide, flooding to the Ganges Delta plain, which is easy to cause large area floods. (Satellite picture, water network dense)
The world's most live volcano Etna volcano is located 3200 meters above sea level, which is the highest living volcano in Europe. The area is 1600 square meters and the susceptor is about 150 kilometers long. 2.5 million years ago is already a living volcano, and the event center is more than one place. The mountain's current structure is the result of at least two major eruption centers. Historical bruises occurred in 475 BC. Record the number of injection of 210 times. The most violent eruption is from March to July, 1669, sprayed from more than 800 million cubic meters of lava. Three hillside vegetation distribution three strips.
