The world most of South America Ecuador thickness of Mount Chimborazo. From the center of the Earth to the mountain peak 6384.1 km. Chimborazo Summit West is located in the Andes cordillera, 6310 m above sea level, is Ecuador's highest peak. Had long been incorrectly identified as the highest peak of the Andes. It is a dormant volcano crater, there are many, many mountain glaciers, at about 4694 meters above the sea, covered with snow all the year round. 1880 United Kingdom alpinist E-Burr's first landing on the Summit. Here is the central plateau region of Ecuador, the main local to agriculture and livestock, mainly sheep, dairy, cereals, potatoes, fruit and fibre plants, etc. The world's highest plateau in the Tibetan plateau is the largest plateau in China, which is also the world's highest plateau, therefore a "known as" the roof of the world. Qinghai-Tibet plateau, an area of 240 million square kilometers, mostly at 3500 m above sea level and above, including all of the Tibet and Qinghai, Sichuan, Xinjiang and Gansu, Yunnan in the South. Plateau around the mountains around the Himalayas in the South, North and Altun, Kunlun mountains, West to the East, Karakorum, Hengduan Mountains. Plateau has tanggula mountains, mountain, gangdese nyainqentanglha mountains, etc. These mountains are more than 5500 meters, of which there are 16 Himalayan mountain more than 8000 meters. Plateau was separated into many mountains basin, loess. The numerous lakes, Lake, Nam are inland salt water lake, is rich in salt, borax, Glauber's salt, etc. Plateau is the birthplace of many great rivers of Asia, such as the Yangtze River, the Yellow River, Lancang and nu River, the River, have originated in this, the water is rich in resources. Because the terrain is high, low, in most parts of the heat more than 4500 metres the hottest month average temperatures below 10 degrees Celsius, there is no absolute frost-free period, cereals to mature, only suitable for grazing. Pastoralists to resistance possession of Alpine yak, sheep, goats. 4200 m Valley can be grown crops, barley, wheat, peas, potatoes, rapeseed, cold-resistant species. Yarlung zangbo River Valley in the low-latitude cold in winter, the winter wheat can be safe. Plateau on many hydropower station, coal mines, steel mills, chemical plants, wool factory, paper mill. Currently, Sichuan, Tibet, Yunnan and Tibet, Tibetan, etc 4 Highway into the plateau, near the railway will also be built in the plateau. Civil aviation flight pass Xining, Golmud, Lhasa. The world's largest desert in the North Africa most of the plateau is called the Sahara desert, but the real sand only one-fifth of the total area. Desert, Sarir and stone desert. The three types of terrain is inlaid distribution. Sahara desert almost the entire North Africa, the West Atlantic Ocean, North Atlas mountains and Eastern Mediterranean, Arabian Sea, the South and the Sahel (Sahel is a half-desert dry steppe transition zone, full of thorns and shrubs). Western Sahara, Morocco, Algeria, Tunisia, Libya, Egypt, Mauritania, Mali, Niger, Chad and Sudan in 11 countries in the region. The characteristics of the terrain here is: seasonal overflow of shallow basins and large lowland OASIS; wide Stony Plain, covered with rock plateau; steep mountains, beaches, dunes and right beside you. Soil organic matter content in General, not suitable for biological growth, depression of the soil often salt. At about 500 million years ago, it has become the climate of the desert. Since then, dry and wet. Current desert mainly in two climate zones. North to dry subtropical climate, its seasonal climate change and the daily temperature differences are great. Precipitation is concentrated mainly in the winter, but in some dry regions, common in summer Heartthrob flood. Spring often has the hot air from the South, with the sand. Southern part of dry tropical climate, the winter often come from the North-East of sandy. Vast Sahara in many areas, there is no certainty that only oasis regions settled. Plants for various herbs; Palm; tamarix spp. and Robinia tree, animals such as Hare, Porcupine, Gazelle, Chameleon, Cobra, etc. Here full of metal ore, petroleum, groundwater, however due to limited the development of transport. The world's largest ocean Pacific nanqi Antarctic, North to the Arctic, the West and Asia and Australia, East Territories South and North America. Approximately one-third of the area of the Earth, is the world's largest ocean. Its area, not including the nearby is the sea, about $ 250 thousand square metres. The second area of the Atlantic Ocean twice, and the water capacity of more than two times. More than include Antarctica, Earth's land area combined. Average depth (not including in the case of sea) 4280 m. There are many in the case of the Western Pacific Ocean, the Bering Sea from North to South as, Okhotsk Sea, sea of Japan and the Yellow Sea, East China Sea and South China Sea. East River Heilongjiang, Yellow River, the Yangtze River, the Pearl River and the Mekong River have been in the case of sea into the Pacific Ocean. North East of 150o than Western gentle ocean floor. Western Pacific underwater 600 meters above the ridges forming islands in some places. From the Northwest Pacific Ocean to the South of the Aleutian Ridge extends to the thousand islands, Ogasawara, Mariana, Yap and Palau; to the East from Palau to Bismarck, Solomon and Santa Cruz; and finally from Samoa to the South to Tonga, kermadec, Chatham and Macquarie. Due to the North of the land and sea, and the proportion is higher than the land south of the ice sheet in Antarctica, North Pacific ocean water temperature higher than the South Pacific. Equatorial latitudes and variable wind sea salt content below the letter flies. On the Pacific vertical currents impact generated around the Antarctic continent. Polar surrounding density of sea water to sink, and then spread to the North Pacific in most of the underlying components. Deep cold water in the Western Pacific to compare distinct currents from the Antarctic to Japan near the beiliu. The mainstream of the deep sea to bring the cold water flows into the tributaries of the East and then in the hemispheres are flowing to the polar regions. Abyssal circulation from the adjacent ocean currents converge in surface water sinks. In the Pacific tropical convergence zone in South latitude 35o to 40o farther from the equator, between the sea, the greater the depth, the most important convergence zone at latitude 55 ° c to 60 degrees. The world's largest drop waterfall Angel Falls, also known as the Churun ar falls. Located in Bolivar State in Venezuela in Guyana plateau, the Caroni River tributaries rise moron. Waterfalls 979 m, width 150 m at the end. Waterfall from the flat-topped plateau Auyan Tepui Telok, almost untouched cliffs. In 1935, the United States explorers Angel found this waterfall, the passenger after the AngelThe aircraft crashed near the waterfall, to commemorate him, Venezuela Government falls to Angel named. World watershed area's largest river basin in the Amazon is the world's largest river, the Amazon River flows through the Amazon is the world's largest plain. Amazon is the world's largest, river flow in the area of the largest rivers. Its length is second only to the Nile River (about 6400 km), the second river in the world. It is estimated that all in the Earth's surface, flows of water about 20-25% in the Amazon. Mouth width up to 240 km, flood stage flow up to 18 million cubic metres per second, is 10 times the Mississippi River. Reducing water demand is so great, so that the distance from the shore of the sea within 160 km fades. Known more than a 1000 tributaries, of which 7 length more than 160 km/h. Amazon deposits of fertile silt to nourish the 65000 km2 of area, its watershed area of 705 000 sq km, almost any other in the world, the great river basin. The famous Amazon rainforest it grows in the Amazon basin. There is also the world's largest plain (area of 560 million square kilometers). Plain, flat terrain, most magnanimous and 150 m above sea level, therefore here the River meandering River, the large lake. Rainy, humid and continuous high temperature is its significant climatic characteristics. Here lies the world's rich and diverse biological resources, various biological up to millions of species. The world's tallest sea water temperature in the Red Sea is located on the Arabian Peninsula in the North-East and Africa, between the long and narrow shape, from the Northwest to Southeast 1900 km length, maximum width 306 km, an area of 45 000 square kilometres. Red Sea North Fork into two small Bay, West to Suez, and runs through the Suez isthmus of Suez Canal and the Eastern Mediterranean; East to the Gulf of Aqaba. Press the seafloor spreading and plate tectonics theory that the Red Sea and Gulf of Aden is the embryonic form of the ocean. According to studies, the Red Sea bottom is the ocean of Silicon magnesium layers of rock, the Department is also at the bottom of the shaft is horizontal mid-ocean ridge broken long crack and rupture zone. The continent of Africa and the Arabian Peninsula began separation in 2 million years ago of the Miocene, currently at the rate of 1 cm to continue to expand. Is recorded in the Red Sea coast of the Strait, steep shore many coral reefs, small natural harbour. The average depth of the Red Sea, 558 m maximum depth 2514 m. Both sides of the Red Sea is something tropical desert jiazhi, perennial sultry air, dust, bright day. Precipitation, evaporation is very high, is the world's water temperature and salinity as one of the most high waters. The average surface temperature for August 27 to 32 degrees Celsius. The world's light Haibo Luo and sea is the Atlantic Ocean into the North Sea Continental Europe. -Northeast-southwest direction. An area of 42 000 square kilometres. General depth of 40-100 meters, the deepest 470 m. General water salinity in parts per thousand of 34 to 37 per thousand. Baltic Sea surface salinity of the sea from the West 8 per thousand to millions of 11, down to the middle of 6 000 to 8 000 and 2 000 in the eastern part 2. World salinity minimum sea. The coastline of the Baltic Sea Island of many, many twists and turns, Harbour. 250 River injection. It is important for maritime transport paths in Northern Europe. North and East of the freezing period up to three to four months, generally do not fall in the South. An important Harbour having along the coast of St. Petersburg, Helsinki, Stockholm, Copenhagen, etc. The world's largest freshwater lake, Lake Superior, the Northwest and Great Lakes of North America's largest, is the world's largest freshwater lake in the world after the Caspian's second largest lake (Caspian is a salt water lake). The North-East of the Lake as Canada, to the South-West of the United States. Lake West 616 km north to South the widest branch 257 kilometres, Lake average elevation 180 meters, water area 82103 square kilometers with a maximum depth of 405 m. 1.2 million cubic kilometres of water storage capacity. There are nearly 200 rivers into the Lake, the Nipigon and the St. Louis River, to the maximum. The main island in the Lake have Royal Island (one of the United States National Park), Apostle Islands, Michipicoten Island and St. Ignace. More along the Lake, the scenic woodlands, sparsely populated. Lake Superior, lake water is clear, the Lakes more waves in winter and cool in summer. Seasonal fishing and hunting and tourism project for the main local entertainment. There are many mineral deposits. There are many natural harbors and ports. The main ports of Canada and the United States in Thunder Bay Tower Cornett, etc. Navigation throughout the year for a period of 8 months. The Lake of France in 1622 the explorers discovered that the name is taken from the French Lake, which means "Lake".
