Rivers and Streams
Geographers generally refer to all rivers and streams as streams, regardless of how big they are. Streams have an important job. They drain the landscape, and move water and minerals towards the Earth’s oceans.
As water drains, it generally begins in small creeks, which flow into larger and larger streams, and eventually into powerful flowing rivers. The largest river on Earth is the Amazon, which drains much of South America. The largest river in North America is the Mississippi River, which drains over 40% of that continent.
