Characteristics and causes of the Amazon River
Characteristics of Amazon river flow:

1, large flow (located near the equator, controlled by the equatorial low pressure belt, with abundant precipitation)

2. The water level changes little, and there is no obvious flood season (tropical rain forest climate, abundant precipitation throughout the year).

3. The basin is vast (located in Amazon Plain)

4. The sediment concentration in the river is small (the tropical rain forest is widely distributed with good vegetation coverage).

5. Abundant hydropower resources (rivers flow through mountainous and plain areas, with large drop and large water volume).

6, no ice age, no ice flood phenomenon (located in the tropics, rivers do not freeze).

The origin of the Amazon River:

1. Topographic reasons: The northern part of the Amazon Plain is Guyana Plateau, the southern part is Brazil Plateau, and the western part is Andes, forming a funnel-shaped terrain that is open to the east. The trade winds in the northeast and southeast of the Atlantic Ocean rise to form a large amount of topographic precipitation, which is abundant. Plain terrain is conducive to water collection.

2. Geographical location: The equator passes through the Amazon Plain and belongs to the tropical rainforest climate. It is hot and rainy all year round, with sufficient precipitation. There is a warm Brazilian current along the coast.

Extended data:

The Amazon river basin is high in the west and low in the east, high in the south and low in the north. The upstream source is the Andes and the alluvial system along the Pacific coast, with an altitude of more than 3000 meters; Both sides of the main stream are mostly Andes alluvium and inland alluvium below 200 meters.

To the north is the Guiana Plateau (300-400 meters above sea level) and to the south is the Brazilian Plateau (300- 1500 meters above sea level). Amazon river basin is a huge depression, which was a sunken deep-sea trough before Cenozoic, and was later filled with a lot of sediments. This huge depression spreads out in a skirt shape in the upper reaches of the Amazon River.

Located between two ancient but not too high crystal plateaus: the rugged Guiana Plateau in the north and the Lower Brazil Plateau in the south. In Pliocene, the Amazon river basin was a huge freshwater lake. At some point in Pleistocene, it suddenly rushed into the Atlantic Ocean, and the river and its tributaries plunged into the bottom of the Pliocene lake.
