Porosity and Permeability

What is porosity

• Rocks

• The percent of the volume of open spaces in rock or sediment

• Ability rock sediment fluids pass through open spaces/pores

• Nothing

Define permeability

• Water

• Nothing

• Percent of volume of open spaces in rock or sediment

• Ability rock/sediment fluids pass through open spaces/pores

If particle size decreases, permeability

• decreases

• increases

• remains the same

• will sometime decrease and other times increase

Which should have the greatest capillarity based on sediment size?

• A

• B

• C

• D

Put these samples in order from highest permeability to lowest permeability: clay, gravel, & sand.

• sand, clay, gravel

• gravel, clay, sand

• gravel, sand, clay

• clay, sand, gravel

Which of the following materials would act as a barrier to groundwater flow?

• gravel

• sand

• clay

Which diagram represents the soil with the greatest permeability?

• Choice 1

• Choice 2

• Choice 3

• Choice 4

Water flows through permeable materials ____________________ than impermeable materials.

• slower

• faster

What is the relationship between soil type/particle size and permiability (as shown by the bar graph below)?

• The larger the particle size, the slower the permeability rate

• The smaller the particle size, the faster the permeability rate

• There is no relationship between particle size and permeability

• The larger the particle size, the faster the permeability rate

Impermeable materials...

• have an abundance of pores.

• let water in.

• have little to no pores.
