How does groundwater occur?

• It doesn't occur

• Rain seeps into the ground until it is completely saturated

• it just happens at random

• When water runs off the surface due to maximum saturation

If water can easily move between cracks of a rock, we can say that...

• water is permeable

• rock is permeable

• rock is impermeable

• water is impermeable

A porous rock can be impermeable

• true

• false

______ is more permeable since water passes through it

• gravel

• sand

• clay

• Silt

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

How does porosity affect permeability?

• Soil has to be porous to be permeable

• No effect

• Some kinds of soil can be porous but NOT permeable

• Soil has to be permeable to be porous
