The Water Cycle

What is the Water Cycle?: 

What is the Water Cycle? Water is always moving between the atmosphere (troposphere) and surface of Earth. Each component of the water cycle process has certain conditions under which each form of precipitation develops.

Components of the Water Cycle: 

Components of the Water Cycle Precipitation Evaporation Transpiration Condensation Run-Off

Precipitation: 

Precipitation After condensation occurs (forming clouds); water droplets fall in various forms of precipitation – rain, snow, freezing rain, sleet, or hail, depending upon weather conditions. Temperature variations within clouds and/or within the region between the cloud and Earth allow for the various forms of precipitation.

Types of Precipitation: 

Types of Precipitation rain sleet snow f reezing rain hail

Evaporation: 

Evaporation Water enters the atmosphere as water vapor

Transpiration: 

Transpiration Plants releasing water vapor

Condensation: 

Condensation Condensation happens in the atmosphere as water vapor changes to water droplets . 1. Clouds 2. Dew : when water vapor condenses directly on a surface 3. Frost : when water vapor changes from gas to ice crystals on a surface (freezing temps)

Run-Off: 

Run-Off If precipitation falls on land surfaces, it always attempts to move back toward sea level as surface-water flow or groundwater flow .

Run-Off: 

Run-Off Water will remain on the surface when the surface is not porous or the precipitation is falling too fast for the water to sink into the ground. Water will sink into the ground when the surface is porous and there is lots of space in the soil to hold the water.
