Water Cycle Definitions

Evaporation
Occurs when radiant energy from the sun heats water, causing the water molecules to become so active that some of them rise into the atmosphere as vapor.
Condensation
The process of water changing from a vapor to a liquid. Water vapor in the air rises mostly by convection. This means that warm, humid air will rise, while cooler air will flow downward. As the warmer air rises, the water vapor will lose energy, causing its temperature to drop. The water vapor then has a change of state into liquid or ice.
Precipitation
Water being released from clouds as rain, snow, sleet, or hail.
Infiltration
Process when water seeps through the ground
Runoff
Precipitation that reaches the surface of the Earth but does not infiltrate the soil.
Transpiration
ccurs when plants take in water through the roots and release it through the leaves, a process that can clean water by removing contaminants and pollution.
