Water Cycle

Water Cycle

Water constantly gets cycled through the environment, from rain to rivers to oceans, to the sky again through evaporation....and back again

Runoff, Groundwater, and Aquifers

Water is transported and collected through its movement on the surface of the Earth. There are almost 200,000 aquifers that store water underground

Aquifer

An aquifer is an underground layer of rock that holds groundwater. Groundwater is rain or melted snow that has seeped into the ground and is held there. Aquifers are filled slowly. For this reason, aquifers can dry up when people drain them faster than they can be refilled—a process called aquifer depletion. Aquifers can be drained by man-made wells or they can flow out naturally in springs.
