Explanation
The Amazon Basin in South America constitutes the largest drainage system in the world by volume. Its geographical features are defined by the Andes Mountains to the west and the vast lowlands that support the Amazon Rainforest.Statement 1 is Correct: The Amazon River originates in the Andes Mountains of Peru (in the west) and flows across the South American continent in a general west-to-east direction to reach the eastern coast.
Statement 2 is Incorrect: The river drains into the Atlantic Ocean, not the Pacific Ocean. The Andes Mountains act as a drainage divide, preventing the river from flowing westward into the Pacific.
Statement 3 is Incorrect: The Amazon River does not flow as a single channel; it is fed by a massive network of over 1,100 tributaries. Many of these tributaries, such as the Madeira, Negro, and Purus, are major rivers in their own right. The system forms an intricate dendritic drainage pattern.
Key Takeaway: The Amazon River flows from the Andes (West) into the Atlantic Ocean (East) and is supported by the world's most extensive network of tributaries.
