GEOLOGY

Detailed explanation-1: -Runoff is precipitation that does not soak into the soil but instead moves on the Earth’s surface toward streams. Streamflow is water moving across the Earth’s surface in streams.

Detailed explanation-2: -Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. Runoff can come from both natural processes and human activity.

Detailed explanation-3: -The difference between runoff and groundwater is that runoff is water flowing on the ground and groundwater is water that moves downward into the ground.

Detailed explanation-4: -Rivers are a major type of surface water. Surface water is a key component to the hydrologic cycle. Surface water is any body of water above ground, including streams, rivers, lakes, wetlands, reservoirs, and creeks.
