Water that lands on soil can
infiltrate (sink in) or run off (move over the surface).
Evaporation is greatest when it is
hot, dry, and windy -- also increase surface area.
Condensation is when
water vapor turns into liquid water
Transpiration is when
water vapor enters the atmosphere through plants.
Zone of Aeration is the
air between soil
Zone of Saturation is the
water between soil (think saturated sponge).
The water table is the
boundary line that separates the two zone.
Infiltration occurs when the land is
permeable, unsaturated, low slope, not frozen.
Runoff occurs when the land is
impermeable, saturated, steep slope, frozen ground.
