Earth's Water

What is an aquifer?

• a body of permeable rock which can contain or transmit groundwater.

• a well in which water is under pressure especially : one in which the water flows to the surface naturally.

• confining layer

• solid rock underlying loose deposits such as soil or alluvium.

What is an confined aquifer?

• a well in which water is under pressure especially : one in which the water flows to the surface naturally.

• solid rock underlying loose deposits such as soil or alluvium.

• an aquifer below the land surface that is saturated with water with layers of impermeable material are both above and below.

• water that collects on the surface of the ground.

unconfined aquifer

• a large natural stream of water flowing in a channel to the sea, a lake, or another such stream.

• an aquifers into which water seeps from the ground surface directly above the aquifer.

• aquifers with which an impermeable dirt/rock layer exists that prevents water from seeping into the aquifer from the ground surface located directly above.

• a large body of water surrounded by land.
