Water, Energy, and Climate Vocabulary
Water cycle- The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration
Infiltration- percolation: the slow passage of a liquid through a filtering medium; "the percolation of rainwater through the soil"
Subsurface water- water that exists in the lithosphere whether in the unsaturated or vadose zone, or the saturated zone.
Runoff- The draining away of water (or substances carried in it) from the surface of an area of land, a building or structure, etc
Zone of saturation- The phreatic zone, or zone of saturation, is the area in an aquifer, below the water table, in which relatively all pores and fractures are saturated with water. The phreatic zone may fluctuate with changes of season and during wet and dry periods.
Zone of aeration- The locus of points just above the water table where soil pores may either contain air or water. This is also called the vadose zone. Water in the zone of aeration does not flow into a well.
Water table- the upper limit of the underground zone of saturation or the top surface on an aquifer
Groundwater- water that enters the ground and occupies free space in soil and sediment as well as openings in bedrock, including cracks and spaces between grains
Porosity- the ability of a material to hold water in open spaces, or pores
Sorting – the separation of particles of sediment as a result of differences in their shape, density, or size
Permeability- the ability of soil or sediment to allow water to flow through it
Capillarity- the tendency of a substance to pull water into tiny spaces, or pores, by adhesion
Capillary water- Water held as a film around soil particles and in tiny spaces between particles. Surface tension is the adhesive force that...
