The Water Cycle Ms Pearson’s Class
The Water Cycle (also known as the hydrologic cycle) is the journey water takes as it circulates from the land to the sky and back again.
ABOUT THE WATER CYCLE • Earth’s Cycle is always in movement • Also known as the hydrologic cycle, it is a continuous movement of water on, above, and below earth’s surface. • Since it is truly a CYCLE there is no beginning or end.
PRECIPITATION • Is condensed water vapor that falls to the Earth's surface. • RAIN • SNOW • HAIL • FOG • SLEET
SNOWMELT • Is the runoff produced by melting snow.
RUNOFF • The variety of ways by which water moves across the land • Surface runoff • Channel runoff • As it flows the water may: • GO INTO THE GROUND • EVAPORATE INTO THE AIR • BECOME STORED IN THE LAKES OR RESERVOIRS • BE EXTRACTED FOR AGRICULTURAL OR OTHER HUMAN USES
INFILTRATION is the flow of water from the ground surface into the ground SURFACE FLOW The flow of the water underground.
EVAPORATION • The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the atmosphere.
CONDENSATION • Is the transformation of water vapor to liquid water droplets in the air. • CLOUDS • FOG
