Step-by-step explanation:
The Amazon and its tributaries flow in the east direction.
The Amazon River, which is more than 2,000 miles long and has an enormous drainage basin, is located in South America. It drains the entire interior region of the continent, covering 40 percent of it. The river's many tributaries move massive amounts of water through the Amazon Basin.
Examples of the Amazon's major tributaries include the Rio Negro, the Madeira, and the Xingu. These tributaries are major rivers in their own right and they flow in various directions throughout the Amazon Basin.
