Precipitation falls on the ground, but what happens to that water depends greatly on the geography of the land at any particular place.

The movement of water on land and through the Earth's many layers is evaluated using ground and satellite measurements along with computer models.

Groundwater gains and losses vary dramatically on our planet as a result of precipitation levels and the effects of evaporation due to sunlight.

Water on land is diverted into rivers or stored underground in aquifers (multi-colored areas) for consumption by plants, animals and humans.
