Only 3% of Earth’s water is freshwater.
Only 30% of ALL freshwater is in liquid form:
1% on the surface
29% underground

Surface water comes from precipitation and moves due to gravity.

•Surface water runs downhill due to gravity.
•The area of land that contributes water to a river system is called a watershed.
