Water Runoff and Infiltration Concepts

The video tutorial covers the final lesson on groundwater and the water cycle, focusing on the processes of infiltration and runoff. It explains how water infiltrates the ground, becoming filtered and clean, and contrasts this with runoff, where water moves over the land. The tutorial discusses factors affecting these processes, such as permeability, slope, and vegetation, and explains how saturation impacts water movement. The lesson concludes with a summary and information on upcoming assignments.

What is the primary difference between infiltration and runoff?

• Infiltration is the process of water evaporating, while runoff is water freezing.

• Infiltration involves water entering the ground, while runoff involves water moving over the ground.

• Infiltration and runoff are the same processes.

• Infiltration involves water moving over the ground, while runoff involves water entering the ground.

How does increased permeability affect infiltration?

• It decreases infiltration.

• It causes water to evaporate.

• It has no effect on infiltration.

• It increases infiltration.

What happens to runoff when the ground is impermeable?

• Runoff stops completely.

• Runoff decreases.

• Runoff remains the same.

• Runoff increases.

How does a steep slope affect water infiltration?

• It increases infiltration.

• It decreases infiltration.

• It has no effect on infiltration.

• It causes water to evaporate.

What is the effect of a flat surface on runoff?

• It decreases runoff.

• It increases runoff.

• It causes runoff to stop completely.

• It has no effect on runoff.

How do plant roots affect soil permeability?

• They decrease soil permeability.

• They have no effect on soil permeability.

• They increase soil permeability.

• They cause soil to become impermeable.

What happens to runoff when vegetation is removed?

• Runoff stops completely.

• Runoff decreases.

• Runoff increases.

• Runoff remains the same.

What is the effect of ground saturation on infiltration?

• It decreases infiltration.

• It increases infiltration.

• It causes infiltration to stop completely.

• It has no effect on infiltration.

How does saturation affect the movement of water already in the ground?

• It allows water to continue moving through the ground.

• It has no effect on the movement of water.

• It increases the movement of water.

• It stops the movement of water.

What is the relationship between saturation and permeability?

• Saturation does not affect permeability.

• Saturation makes the ground impermeable.

• Saturation increases permeability.

• Saturation decreases permeability.
