ES - Groundwater Exam Review 21-22

Front

What is infiltration?

Back

The process by which water sinks into the ground.

Front

What is porosity?

Back

The measure of the void spaces in a material, indicating how much water it can hold.

Front

What is permeability?

Back

The ability of soil to transmit water through its pores.

Front

What is capillarity?

Back

The ability of water to rise in narrow spaces against gravity, often seen in soil.

Front

What happens to runoff when soil is impermeable?

Back

More runoff occurs because water cannot infiltrate the soil.

Front

Organize the particle sizes from smallest to largest: clay, silt, sand.

Back

Clay, silt, sand.

Front

What does high porosity indicate about soil?

Back

It indicates that the soil has a large amount of space between particles, allowing for more water retention.

Front

What is the relationship between infiltration rate and soil texture?

Back

Finer soils like clay have lower infiltration rates compared to coarser soils like sand.

Front

What is the effect of vegetation on groundwater recharge?

Back

Vegetation helps increase groundwater recharge by slowing down runoff and allowing more water to infiltrate.

Front

What is groundwater?

Back

Water that is stored underground in soil and rock formations.
