What is an aquifer?

• An aquifer is an above-ground layer of impermeable rock that holds water underground under pressure, causing geysers.

• An aquifer is an above-ground layer of permeable rock that holds water, allowing it to be used as a source of drinking water.

• An aquifer is an underground layer of impermeable rock that forces water to the surface, causing floods.

• An aquifer is an underground layer of permeable rock that holds water, allowing it to be used as a source of drinking water.
