The Amazon River is located in Brazil, South America, near the equator. It has a tropical rainforest climate, characterized by high temperatures and heavy rainfall all year round, with an average annual precipitation of more than 2,000 mm. The Amazon Plain is bordered by the Andes Mountains to the west, the Guiana Plateau to the north, and the Brazilian Plateau to the south. The north, west, and south sides are high, and the middle is low, which is conducive to collecting rainwater. The favorable terrain and rainy climate make the flow of rivers in the Amazon Plain area large.
