Water Cycle IAN 2

8.  Energy-      is either added to or taken away during each step to cause the changes!

9. evaporation-     water absorbs enough heat to change into a gas called water vapor.  Water vapor is INVISIBLE!!!  Molecules gain energy, energy is added.

10.  We CANNOT see water vapor!

11.  salt-      stays behind in the ocean and ONLY the water evaporates.  Oceans provide most of the water vapor in the atmosphere.

12. transpiration-       plants losing water vapor to the air through leaves (plant sweat!)  Molecules gain energy, energy is added.

13. condensation-       water vapor cooling down or losing enough energy to change into tiny droplets of water.  Molecules lose energy, energy is lost.

14. clouds-     are caused by condensation.  Clouds are tiny droplets of water, they are NOT water vapor!
