The earth has a limited amount
of water. That water keeps going around and around and around and
around in what we call the
"Water Cycle". This cycle is made up of a few main parts: evaporation, condensation and precipitation.
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.
Condensation is when water vapor in the
air gets cold and changes back into liquid, forming
clouds.
Precipitation
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.
Collection is when water falls back to earth as precipitation, it may fall
back in the oceans, lakes or rivers or it may end up on land.
When it ends up on land, it will either soak into the
earth and become part of the “ground water” that plants and
animals use to drink or it may run over the soil and collect in
the oceans, lakes or rivers where the cycle starts all over again. Using this webquest, you will gain Scientific knowledge of the Water Cycle. With this knowledge you will create a representation of the Water Cycle and present the information to others.
