GEOLOGY

Detailed explanation-1: -The statement mentioned above is True. All the water that falls in the streams with the help of a watershed is accomplished by precipitation.

Detailed explanation-2: -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-3: -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-4: -The principal climatic factors affecting runoff variation are precipitation and temperature. Precipitation change will directly disturb the discharge of the drainage basin, whereas temperature change influences the runoff by altering the capacity of evaporation.

Detailed explanation-5: -Surface runoff is precipitation runoff over the landscape.
