SCI CHP 15: Part 2 - Groundwater Movement Factors & Influences

Front

What is porosity?

Back

Porosity is the amount of water a sediment can hold.

Front

What is permeability?

Back

Permeability is the ability of a material to allow fluids to pass through it.

Front

How does gravity affect groundwater movement?

Back

Gravity pulls water downward, influencing how quickly it moves through soil and rock.

Front

What is the relationship between porosity and water retention?

Back

Higher porosity means more space for water, allowing sediments to hold more water.

Front

What is the difference between porosity and permeability?

Back

Porosity measures how much water a material can hold, while permeability measures how easily water can flow through it.

Front

What type of soil has high porosity and low permeability?

Back

Clay has high porosity but low permeability.

Front

What is the effect of viscosity on groundwater movement?

Back

Viscosity is NOT a factor that affects groundwater movement.

Front

What determines how much water soil can absorb?

Back

Porosity determines how much water the soil can take in.

Front

What factors influence the speed of groundwater movement?

Back

Permeability and gravity determine how fast water can move underground.

Front

What is an example of a material with high permeability?

Back

Sand is an example of a material with high permeability.
