Water cycle
~A model, often a diagram, used to illustrate the movement and changes of state of water at and near Earth's surface

~Also known as hydrology cycle
~ The change in state from liquid to a gas

~Also know as vaporization
The process by which plants release water vapor into the atmosphere as part of their life functions (photosynthesis)
The change in state or phase from a gas to a liquid
Falling liquid or sold water from the clouds toward Earth's surface
All the natural liquid water flowing on Earth's solid surface including stream flow
~Water sinking into the upper parts of Earth's lithosphere due to gravity becoming subsurface water

~Also known as seep
The change in state of a liquid to a solid by the removal of heat
The change in state from a solid to a liquid
Zone of Saturation
The portion of soil and bedrock that is below the water table where the pores are filled with ground water
Zone of Aeration
The materials on Earth's surface down to the water table where the pores are only partly filled with liquid water. Air fills the rest of the pores
~The area of land drained by any one stream

~ Also known as a drainage area
Small stream or river that flows into a larger stream or river
The surface water found beneath the water table in the Zone of Saturation
Percentage of open space (pores and cracks) in a material compared to its total volume
The degree to which a porous material (such as rock or soil) will allow fluids to pass through it
Permeability rate
The speed at which a certain amount of fluid can pass through a porous material
The process by which water is drawn into openings due to the attractive force between water molecules and surrounding materials
Water retention
Storing or retaining of precipitation in Earth's land surfaces as ice or snow or as liquid water on trees and other plants
water table
the interface between the Zone of Aeration and the Zone of Saturation
