is fresh water on Earth's land surface.

as streams and rivers move across the land, they form a flowing network of water called a river system.

the area of land that is drained by a river is known as a watershed.

Water beneath the Earth's surface in sediment and rock formations is called groundwater.

an underground formation that contains groundwater is called an aquifer.

is the percentage of the total volume of a rock that has spaces. (pores).

the ability of rock or soil to allow water to flow through it is called permeability.

Earth's surface from which water percolates down into an aquifer is called a recharge zone.
