The Amazon River is located in the tropical rainforest climate zone near the equator, where it is hot and rainy all year round, with extremely high precipitation. In addition, the terrain is high on the north, west and south sides and low in the middle, which is more conducive to the collection of rainforests. The Amazon River has a flow of up to 219,000 cubic meters per second, making it the river with the largest water volume in the world. Its flow is several times greater than the sum of the Nile River, the Yangtze River and the Mississippi River, so the Amazon River has a larger flow than the Mississippi River.
