Hydrologic Cycle



Hydrologic Cycle:
The water cycle describes the continuous movement of water on, above, and below the Earth's surface.

Evapotranspiration:
The sum of evaporation and plant transpiration from Earth's land surface to the atmosphere.

Precipitation:
Any product of the condensation of the water vapor in the atmosphere being pulled down by gravity to the Earth's surface.

Condensation:
The change of a gas into liquid droplets.

Evaporation:
The process of a liquid turning into a gaseous state, such as what happens when water is boiled and vapor rises.

Transpiration: Similar to evaporation however the loss of water is in the leaves, or roots of plants.

Run Off:
Water flow that occurs when the ground has soaked in as much as it can and water can not be absorbed anymore.

Solution: A homogeneous mixture of two or more substances.

Suspension:
A mixture where fine particles are suspended in a fluid by their buoyancy.
