The Water Cycle
The sun acts as a pump,
keeping water going around and around.
(Source Unknown)
1. Condensation -
Water vapor forms clouds. When the clouds cool, the vapor becomes
liquid.
2. Precipitation - Liquid
is heavier than vapor. Gravity pulls the liquid down on the earth
as rain.
3. Runoff - When the rain
hits the earth, it runs across the land into lakes, streams &
oceans.
4. Percolation - Some of
the rain soaks into the ground and travels through rocks, gravel
& sand.
5. Ground Water - Water
that percolates down through the ground is stored in aquifers.
6. Discharge - Some ground
water eventually travels back to the earth's surface.
7. Evaporation - The sun
heats surface water, making it into vapor that rises into the
sky.
