Water
e l y c c
Cycle
• describes the existence and movement
of water
on, in, and above the Earth.
• Earth's water is always in movement and is
always changing states, from
liquid to vapor to ice and back again.
Evaporation is when the sun heats up water in rivers
or lakes or the ocean and turns it into vapor or
steam. The water vapor or steam leaves the river,
lake or ocean and goes into the air.
Do plants sweat?
People perspire (sweat) and
plants transpire.
Transpiration is the process by
which plants lose water out of their
leaves.
Water vapor in the air gets cold and
changes back into liquid, forming
clouds.
occurs when so much water has condensed that
the air cannot hold it anymore. The clouds get
heavy and water falls back to the earth in the form
of rain, hail, sleet or snow.
Some of the water infiltrates into
the ground and
replenish, aquifers (saturated
subsurface rock), which store huge
amounts of freshwater for long
periods of time.
How can you
save water?
1. It is the movement of water that the sun heats up
in rivers, lakes, or ocean?
2. If people perspire, then the plants also what?
3. It is the movement of water that when the
clouds get heavy and water falls back to the
Earth in the form of rain, hail, sleet or snow.
4. What is water cycle? 2pts.
After a plastic bag is wrapped around part of a
plant, the inside of the bag becomes misty with
transpired water vapor.
