Cloud types (cirrus, stratus, cumulus)
Water cycle (evaporation, precipitation, condensation)

I     I. Evaporation 
          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 body of waters and goes into the air.

           A. Bodies of Water

                1. Oceans

                2. Rivers

                3. Lakes

           B. Ground Water

      II. Condensation

           Condensation is the process where water vapor in the air is        ... changed into liquid water. Condensation is crucial to the water    ... cycle because it is responsible for the formation of clouds.

             A. Water Vapor

                  1. Dew

                       The water droplets formed by condensation of water    ..............  vapor on an object with a relatively cold surface.

                  2. Clouds

            B. Water

     III. Precipitation

           When there is so much water that it condensed in the air and    ... cannot hold it anymore. The clouds get heavy and water falls .... back to the earth in different forms.

            A. Snow

                 1.  Sleet

                 2. Hail

            B. Rain

     IV. Collection

           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 and soak ......into the soil.

             A. Bodies of Water

             B. Ground Water

                  1. Springs

                  2. Wells

     V. Transpiration

           Transpiration is  evaporation of water from plant leaves.

           Moisture is carried through plants from the roots to the      ....underside of leaves, where it changes to a vapor and is released   .....into the atmosphere.

            A. Leaves

                 1. Flowers

                 2. Trees

            B. Roots
