Aquifers
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt).
Groundwater
Is the water found underground in the cracks and spaces in soil, sand and rock.
Percolate
(of a liquid or gas) filter gradually through a porous surface or substance.
Lack of water
UN-Water or Water scarcity
Precipitation
Precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds.
Transpiration
The release of water from plant leaves
Snowmelt runoff
Once air temperatures begin to warm above 32 degrees F, however, this snow and ice melts into liquid water and becomes runoff
Condensation
The process of water vapor turning back into liquid water
Sublimation
The process of snow and ice changing into water vapor in the air without first melting into wate
surface flow
The flow of water occurring on the ground surface when excess rainwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
