Amazon River Basin (The southern Guianas, not marked on this map, are a part of the basin.) The mouth of the Amazon River. The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 7,000,000 km 2 (2,700,000 sq mi), [1] or about 35.5 percent of the South ...
Topography of the Amazon River Basin. The Amazon River (UK: / ˈ æ m ə z ən /, US: / ˈ æ m ə z ɒ n /; Spanish: Río Amazonas, Portuguese: Rio Amazonas) in South America is the largest river by discharge volume of water in the world, and the longest or second-longest river system in the world, a title which is disputed with the Nile.

The Amazon rainforest, [a] also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km 2 (2,700,000 sq mi), [ 2 ] of which 6,000,000 km 2 (2,300,000 sq mi) are covered by the rainforest . [ 3 ]
The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. The estimated global total for all rivers is 1.2 × 10 6 m 3 /s (43 million cu ft/s), [ 1 ] of which the Amazon would be approximately 18%.
The Amazon biome has an area of 6,700,000 square kilometres (2,600,000 sq mi). [2] [a] The biome roughly corresponds to the Amazon basin, but excludes areas of the Andes to the west and cerrado (savannah) to the south, and includes lands to the northeast extending to the Atlantic ocean with similar vegetation to the Amazon basin.

Amazon alluvium deposit. The Amazon Basin is a large sedimentary basin (620,000 square kilometres (240,000 sq mi)) located near the middle and lower course of the Amazon River, south the Guiana Shield and north of the Central Brazilian Shield. The basin developed on a rift that originated about 550 million years ago during the Cambrian.
The other major river of this central lowland is the Orinoco River, which has a natural channel linking it with the Amazon. [1] Most of this central lowland is sparsely populated because the soils are heavily leached, but in the south is the very fertile pampas of Argentina—one of the world's major food-producing regions where wheat and beef ...
