What is surface runoff?
Precipitation that runs off the landscape
What keeps the oceans full?
Precipitation, runoff, and discharge from rivers and the ground
Where does much of the water in rivers come from?
Directly from runoff
What happens to the precipitation that falls on the land?
It flows overland as runoff
What is the role of oceans in the water cycle?
Acting as a large storehouse of water that evaporates to become atmospheric moisture
What causes water to start moving when it rains?
The laws of gravity cause water to start moving when it rains.
What is the significance of runoff?
Runoff keeps rivers and lakes full of water and changes the landscape by the action of erosion.
What can flowing water do?
Flowing water has tremendous power and can move boulders and carve out canyons.

During a major storm at Peachtree Creek in Atlanta, Georgia in 2001, the amount of water that flowed in the river in one day was 7 percent of all the streamflow for the year.
