Water Cycle Water circulates from the land to the sky and back again. The sun's heat provides energy to evaporate water from earth's surface.

Evaporation: Type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.

Precipitation: Action of precipitating a substance from a solution.

Condensation: Water that collects as droplets on a cold surface when humid air is in contact with it.

Transpiration: Process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released by the atmosphere.

All of the components in the water cycle are inorganic such as plants and animals

Pathway of Movement: water gets heated from the sun and then evaporates. As a result, the water vapor condenses forming clouds. Water then precipitates from the clouds in different forms which infiltrate back into the ground or flow back into bodies of water

Human Impact: deforestation, irrigation, urbanization, groundwater mining, combustion, storage of water in reservoirs, wetlands
