_______________ is the ability of a substance to allow another substance to pass through it, especially the ability of a porous rock, sediment, or soil to transmit fluid through pores and cracks.

• Permeability

• Runoff

• Pores

• Porosity

As permeability increases

• Infiltration decreases and runoff decreases

• Infiltration increases and runoff decreases

• Infiltration decreases and runoff increases

• Infiltration increases and runoff increases

What is the relationship between particle size and porosity?

• As particle size increases permeability increases

• As particle size decreases permeability increases

• There is no relationship

What type of sediment tends to be the most impermeable?

• sand

• clay

• silt

• rocks

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

What affect does particle size have on permeability

• No effect

• The larger the particles the lower the permeability

• The larger the particles the higher the permeability

• The smaller the particles the higher the permeability

Why does water move slowly through clay or not at all?

• clay has large pore spaces

• clay has hard particles

• clay has very small particles

A porous rock can be impermeable

• true

• false

• sometimes

• never

Which container has the lowest porosity?

• A

• B

• C

• A and B
