All the information about the Amazon River.

Amazon (Portuguese: Rio Amazon; ; Spanish: Río Amazonas), also translated as "Amazon River", located in South America, is the world's largest river with the largest flow, the largest basin, the largest number of tributaries and the second longest river. The flow of the Amazon River reaches 2 19000 cubic meters per second, which is several times larger than the sum of the flows of the other three rivers, namely the Nile, the Yangtze River and the Mississippi River, equivalent to the flow of seven Yangtze Rivers, accounting for 20% of the world's rivers. The basin area is 6910.5 million square kilometers, accounting for 40% of the area of South America. The number of tributaries exceeds 15000.

Because the measurement method of river length is still inconclusive, there are many different opinions about the length of the Amazon River, one of which is the common 6,400 kilometers [2], which is slightly shorter than the Nile in Africa and ranks second in the world. In 2007, a group of scholars from Brazil and Peru claimed to have discovered a new source, and published the measurement results of the river's length of 6992.438+05 kilometers, thus surpassing the Nile to become the longest river in the world [3]. But in fact, the source of this river was discovered as early as 1996 [4] and confirmed by academic circles in 200 1 [5], so the correctness of the so-called "new source of the river" and the "new length of the river" derived from it still needs to be tested by global geographers. The sea water within the range of Amazon River estuary 150km is not salty, and its salt content is quite low. The main channel is 1.5 ~ 12km wide, and there are 3,700km waterways from the estuary to the inland river. Ships can go straight to Iquitos, Peru. Smaller ships can continue to sail 780km to Cape Coward, and even smaller ships can continue to rise. The Amazon River extends from 5 degrees north latitude to 20 degrees south latitude. Its source is in the Andean Plateau, only a short distance from the Pacific Ocean, and it enters the Atlantic Ocean near the equator through Peru and Brazil. East of the Andes, the Amazon rainforest is the largest rainforest in the world, which has important ecological significance. Its biomass is enough to absorb a lot of carbon dioxide. In recent years, protecting the Amazon rainforest has become an important topic. The Amazon rainforest relies on the very humid climate of the Amazon River basin, and the Amazon River and its tributaries 100 slowly flow through this plain with very small height difference. Manaus, a Brazilian city beside the river bank, is 0/600 from the Atlantic Ocean/KLOC. The biodiversity of this rainforest is excellent, with 2.5 million species of insects, tens of thousands of plants, about 2,000 species of birds and mammals, living in one fifth of the total number of birds in the world. Some experts estimate that there are more than 75,000 kinds of trees and 1.5 million kinds of higher plants per square kilometer, of which the plant biomass is 90,000 tons. There are many kinds of aquatic life in the Amazon River. Amazon dolphin is the largest freshwater dolphin in the world, which can reach 2.6 meters in adulthood. And piranhas. They live in groups and may attack people and animals. Although many experts don't think they are that terrible, 198 1 was shipwrecked in Obidos, killing 300 people. There are anacondas in the shallow waters of the Amazon river basin, which are the largest snakes in the world. They spend most of their time in the water, only sticking their nostrils out of the water, but anacondas generally don't attack fishermen. Thousands of fish, crabs and turtles live in this river. & lt/p & gt； & lt/p & gt；

Information about the Amazon River

At present, some Amazon rainforests have been turned into protected areas, such as the Amazon National Park on the Taparros River, covering an area of nearly 10,000 square kilometers. According to the preliminary data released by Brazil's National Space Research Institute, the annual disappearance rate of Amazon forest area has increased to nearly 15%, and the forest area has decreased by 19386 square kilometers. The agency said that this data is based on the comparison of satellite images, but the actual situation may be worse. It is estimated that in 1998/99, the Amazon forest area will disappear 16926 square kilometers, and the final statistics show that the actual forest area will disappear 17529 square kilometers. By 1999, the disappearing area of Amazon forest has reached 569,268 square kilometers, accounting for 14% of the total forest area. The Brazilian government has now turned some Amazon rainforests into protected areas, such as the Amazon National Park on the Taparros River in western Brazil, covering an area of nearly 10,000 square kilometers. However, if the current deforestation rate is not slowed down, Amazon, a vast forest that accounts for two-thirds of the global forest area, will disappear in 2 1 century. The Amazon River originates in the Andes of Peru and crosses the Amazon River in northern South America, with a total length of 6,400 kilometers, which is the second longest river in the world after the Nile. The Amazon River has more than 1.5 million tributaries, and the river flows through all or part of the territories of Brazil, Colombia, Peru, Bolivia, Ecuador, Venezuela, Guyana and other countries, forming a huge river network covering the South American continent. Its drainage area is 7.05 million square kilometers, ranking first in the world, 2.5 times that of the Nile, accounting for about 40% of the land area of South America. Most of the places where the Amazon River flows are equatorial rain forest belts, so the flow is particularly large, ranking first in the world. The average annual discharge of the estuary is 6.5438+200,000 cubic meters per second; The flood season can reach more than 200,000 cubic meters per second. Every year, the amount of water discharged into the Atlantic Ocean from the vicinity of Malajo Island reaches 6,773 cubic kilometers, accounting for 18% of the total amount of water injected into the ocean by all rivers in the world. In the Atlantic Ocean more than 300 kilometers away from the estuary, you can also see the muddy river. The Amazon River is also the longest navigable river in the world. The total length of the main stream from Hekou to Iquitos is 3,598 kilometers, and all the way can pass 3,000-ton ships. 1969, the American geographical society expedition sailed downstream from San Francisco, Peru to Belem, Brazil, with a voyage of 6 187 km. This is unmatched by any river in the world. The name of the Amazon River comes from several sources. One is/kloc-During the exploration of the Amazon River in the 6th century, Spanish Olaiya was violently attacked by local Indian women. These women are brave and fierce, just like the "Amazon" female warrior in Greek mythology. Later, Amazon became the name of this river. Another way of saying it is that the mouth of the Amazon River is trumpet-shaped and the river surface is very wide. When the tide is high, the waves are rough. Locals often sigh "Amazon", which means "surging waves". There is also a saying that the boat often capsizes when the wind and waves are heavy. The name of this river means "destroyer of ships" in the local language. On both sides of the Amazon River, there are endless tropical jungles, and all kinds of trees grow alternately, and large and small rivers become forest paths. There are many kinds of animals and plants in the forest, including hundreds of precious trees such as mahogany and ebony. It is sparsely populated and has little agricultural land. Ships are people's houses and places for activities. Shops and schools are all located on the boat, and even parties, weddings and funerals are held on the boat.

Among the tributaries, 7 are more than 1600 km long; The longest is the Madeira River, which is more than 3,200 kilometers long. Most of the tropical rainforests in the Amazon basin are located in Brazil, with an area about twice that of India and an altitude of no more than 200 meters.
