Amazon River in South America, the Amazon is the world's largest flow, the most extensive river basin, the largest tributary of the river. Capacity of 219,000 cubic meters per second, the Amazon river, the Nile flows than the other three rivers, the Yangtze River, the Mississippi River combined large, accounting for 20% of the world's rivers flow; basin area of 6,915,000 square kilometers, accounting for 40% of the area of South America ; tributaries more than 15,000 bar. Amazon is the world's first river, up to 6,800 km (southern Peru as the source). Amazon extends from 5 degrees north latitude to 20 degrees south latitude, the source in the Andes Plateau, from the Pacific Ocean just a short distance, through Peru and Brazil into the Atlantic Ocean near the equator.
Length of the Amazon River, 6400 km, flows through Peru, Brazil, Bolivia, Ecuador, Colombia and Venezuela, and ultimately into the Atlantic, the longest in South America, the world's largest drainage area and flow of the river.
Amazon River basin area 7.05 million square kilometers, accounting for the total area of the South American continent, 40%; Amazon widest point is about 2,776 km north of Henan (1,725 miles). Amazon River into the Atlantic every year about 6600 cubic kilometers of water, equivalent to the total world's river water into the ocean, 1 / 6.
the world's largest river-Amazon River - topography
Amazon River Amazon River about length 2500 km, divided into upper and lower two. On a section of about 1000 km, drop up to 5,000 meters, high mountains and deep valleys, steep slope current is swift, forming a series of rapids waterfall; the next segment into the two great tributaries of the Amazon River between the two estuaries, because access Amazon plain, slow flowing, meandering stream developed, to the end of the river width of 2,000 meters.
In northern Brazil, the Amazon river depth of 45 meters, width of river 3,000 meters, the flow rate is slow; River Island Island staggered, river reticular distribution, cross the river floodplains 30 to 100 km wide, low-lying, densely along the lake, drainage is not Chang; numerous tributaries on both sides of the river, which originated in the Andes east slope, showing plume distribution. To middle end of the river width to 11 km, the river depth 99 meters.
Amazon River basin from west to east, the south than in the north. Headwaters of the Andes and the Pacific coastal alluvial system, elevation of 3000m above; River cross the Andes, mostly below 200m inland alluvium and alluvium. North to Guyana plateau (elevation 300 ~ 400m), compared with Brazil's south plateau (elevation 300 ~ 1500m).
Amazon River and its tributaries have a large submerged valley. Pleistocene glaciers melt, sea level rise, steep canyons in the sea level has been low for the Pliocene erosion surface, now completely submerged. The ancient sediment basin is a permanent land surface of the soil, most of the Amazon rain forest will be developed on the soil in this. Upstream in the basin (eastern Peru and Bolivia), brush down from the Andes pulse of sediment covering the ancient surface. Amazon has a large lowland flooding every year, but most of the land is hilly "permanent land" (terrafirme), far beyond the flood water level. The growth of tropical rain forest watershed, is the world's largest treasure house of biological resources.
the world's largest river-Amazon river - hydrological characteristics
Amazonian climate
Most parts of the Amazon River area of tropical rain forest climate, annual rainfall of 2,000 mm.
Speed of the Amazon river
Source region on the high mountains and deep valleys, steep slope current is swift, with an average gradient of about 5.2 ‰. After more than a small drop into the plains. River average flow rate of 0.7-1.7 m / sec.
Amazon River runoff
It is estimated that the Amazon River flows all the water surface of the Earth 1 / 5, the average annual flow of the mouth 2 to 220,000 m / s, flood flows of up to 280,000 m 2 / s, more than 10 times for the Mississippi River , a large number of fresh water so far away from the coast 160 km (100 miles) above the waters of the sea salt diluted.
the world's largest river-Amazon River - Major tributaries
Amazon River tributaries over 1,000 km in length more than 20.
Amazon River into the sea before the formation of large braided river network, and with the south of the Tocantins River and Para River confluence, into the Atlantic Ocean. Mouth wide and three hundred twenty kilometers, of which two rivers branching from the horse if the island separated from the island area and an area of very major tributary of the Swiss, by the Mamore River (Mamore) and Beni River in Bolivia than Elijah Beria town (Villa Bella) merged into the North after the flow, as Bolivia and Brazil border river.
Since the Mamore River, the total length of 3,352 kilometers (2,082 miles), the width of about 0.8 km (0.5 miles). Upstream from the mouth of 1,300 kilometers (807 miles) to Wei Liu (Velho) near the port of San Antonio Falls, most of the time available each year through the ship. The total of 19 falls above the waterfall, turbulence. Madeira - Mamore railway from Porto Velho to guajara Millington (Guajara-Mirim), and Madeira upstream phase.
Occasional along the coast Indians and mestizos of Indo-European settlements, the residents collect Brazil nuts and rubber and other forest products. Amazon is Latin America's largest lowland area of about 6,000,000 square kilometers (2,300,000 square miles), almost any other river basins in the world twice.
Amazon River - Natural resourcesAmazon animal shipping resourcesTo the mouth of the Amazon River headwater elevation difference between the small, combined with another in the equatorial rain-fed areas, river deep, wide and flat, the flow rate is very slow, suitable for shipping industry, port of Manaus is the Amazon important port.
Amazon River TourismAmazon has a world of natural wonders - tidal bore, across the South American continent after the Amazon in Brazil into the Atlantic Ocean near the island marajo. The mouth of the Amazon River was a huge horn, trumpet, after the tide into the past and continue to be squeezed into the forefront of uplift can be traced back 600 to 1000 km. Generally 1 meter high tide to 2 m, when the tide up to 5 meters. Brazilian Amazon, the tide referred to as the "wave Rocca," bore when more visitors.Amazon species resourcesAmazon for plant growth, two thousand species of plants, the Amazon rain forest vegetation is rich in different types of plants per square kilometer than 1200 species, a quarter of the world's pharmaceutical raw materials, is to from tropical rainforest plants; the medical profession has been recognized as effective for the treatment of cancer, some plants, 70% is grown in the rainforest.Many trees over sixty meters high, high to low canopy layer. Kudzu, orchids, bromeliads, eager to climb the high branches of plant growth, during which the habitat of monkeys, sloth, hummingbirds, King Kong, parrots, butterflies and countless huge bats. Water live caiman, freshwater turtles and aquatic mammals such as manatees, freshwater dolphins. Jaguars live in the land, slender cat, West (speechless), tapirs, capybaras, armadillos, etc.Live in the Amazon river in the caiman, freshwater turtles and aquatic mammals such as manatees, freshwater dolphins. Jaguars live in the land, slender cat, West (speechless), tapirs, capybaras, armadillos, etc. Another two thousand five hundred kinds of fish, and more than sixteen hundred kinds of birds.Amazon anaconda is the world's largest snake, up to 10 meters, weighing two hundred twenty-five kg more than five meters in length and a half below. Anaconda like nature of water, usually live in the muddy shore or shallow water, feeding birds, turtles, capybaras, tapirs, caimans.
Amazon River - Discover the history of
Amazon Amazon estuary early detection of Europeans, is with the Columbus voyage of the Spanish captain Hiramatsu. He came here in 1500, that is a big freshwater lake.
1541-1542, Spanish German and Austrian Raleigh Mariana by Peru's Napo River downstream, the first boat passing through the Amazon most of the river. He is a Spanish expedition led Pizarro members, starting from Ecuador, to find gold, spices and the legendary El Dorado. But an accident, we finally part of the team led by Pizarro, and finally along the land returned to Ecuador. Finally, only Germany, Austria and Eastern Reilly Maliana and part of the team to the Amazon delta, after arrived in the Caribbean.
German and Austrian Raleigh yana line, along the repeated experience dangerous, often attacked by the indigenous. They had encountered a tribe, the soldiers are all female. Later this spread out, creating a sensation, put the tribal people known as the Amazon (decisions based on ancient Greek mythology, the female warrior), river and hence the name.
