Did you know that the water you drink has been around for thousands of years? It travels around the earth in a path known as the "water cycle."
- Evaporation is the part of the cycle in which water is heated by the sun and becomes a gas or vapor. Draw an arrow, and write the letter "E" next to it to show evaporation.
- Condensation is the part of the cycle in which water vapor is cooled in the air and forms tiny water droplets, seen as clouds or fog. Write the letter "C" over the part of the picture that shows condensation.
- Precipitation is the part of the cycle in which the water droplets collect to form rain or snow and fall to the ground or streams and oceans. Draw an arrow, and write the letter "P" next to it to show precipitation.
- Write "fresh" over fresh water and "salt" over salt water.
Three quarters of the earth is covered with water.
If all of the earth's water = 100 glasses
Then salt water = 97 glasses
And fresh water = 3 glasses
Of all fresh water:
Two glasses are frozen in glaciers
One glass is available to share among all living things, plants, and animals
