Transportation The process by which moisture is carried through plants from roots to small pores on the underside of leaves. This is when it changes to vapor and release to the asthenosphere.
Precipitation Water released from clouds in the form of rain freezing rain sleet snow or heil.
Groundwater The part that continues downward through the soil until it reaches rock material that is saturated and it is water under the surfaces.
Water table the upper surface of underground water; the upper boundary of the zone of saturation. The boundary between the zone of aeration and the zone of saturation the upper surface of underground water; the upper boundary of the zone of saturation. The boundary between the zone of aeration and the zone of saturation.
Runoff Precipitation that flows over land into streams and rivers. This water later enters the oceans.
Artesian wall A well which water is under pressure; especially one in which the water flows to the surface naturally.
Aquifer A body of permeable rock that can contain or transmit groundwater.
Spring The result of an aquifer being filled to the water overflows onto the land surface.
Zone of aeration
The zone nearest to the surface where gaps between soil are filled with both air and water.
Zone saturation Below the zone of aeration where the gaps are filled with water.
Permeable Ability of a substance to allow another substance to pass through it especially the ability of a porous rock sediment or soil to transmit fluid through pores and cracks.
Porosity Quality of being porous or full of tiny holes. Allows water to pass through it.
Non permeable Does not allow water to pass through
