Evaporation In The Atmosphere         Water molecules are constantly cycled through our atmosphere when rain falls, then dries up and eventually falls again. When the various sources of water on the planet "dry", evaporation is occurring. The water molecules gain enough energy through the sun's light or heat radiating from the earth's surface to turn into water vapor. Then, they are released into the atmosphere in the gaseous state.

Condensation In The Atmosphere         As the water vapor rises through the atmosphere, it cools down. The cooler temperatures cause the molecules to condense back into the liquid form. These molecules, though very small, come together to form clouds. As more and more condensed molecules join the cloud, rain drops eventually form. When the droplets become large enough, they fall to the ground as rain.

Evaporation in Daily Life         Evaporation commonly occurs in everyday life. When you get out of the shower, the water on your body evaporates as you dry. If you leave a glass of water out, the water level will slowly decrease as the water evaporates. One important example of evaporation is sweating. The sweat requires energy to evaporate off of your skin. It gets that energy from the excess heat your body is producing, in turn causing you to cool down.

Condensation in Daily Life             Much like evaporation, condensation also occurs in day to day life. When you walk outside on a cold day, you can see your breath as you exhale. The air leaving your lungs is much warmer than the outside air temperature, causing the water vapors to condense into a small mist. Condensation is also seen when you take a hot shower and the bathroom mirror fogs or steams up. As the air heated up it came in contact with the cool mirror and condensation occurred on the surface.
