What is a Stream?
Streams are bodies of water that carry along a clearly defined path, called a channel. Streams may vary in width from a few centimeters to several kilometers. Streams are important for several reasons:
- They carry most of the water that goes from land to the sea. Therefore are important for the water cycle.
- They are a major part of the process of erosion. A lot of the surrounding landscapes are controlled by stream erosion.
- Streams are a major source of water and transportation.
