Answer:
The Amazon River is the largest river system in the world because more than 1,000 creeks, streams, and tributaries drain into the river. No other river in the world matches the amount of water that flows through the Amazon. Although the river is deep and wide enough to be navigable, the Amazon flows primarily through the rainforest. Very few cities are connected by the river, so it is not a busy thoroughfare for large transport or industrial ships.
