This is a power point that addresses the basis of all weather on earth. Why is the sun important? What would happen if the air was the same temperature all over the earth? What are the 3 phases of water? How are the processes of evaporation, sublimation, desublimation involved in weather? Where does all of the water vapor come from and what happens to it once it is in the air? What is relative humidity and how is it related to dew point? Which temperatures can hold more actual humidity...warm or cold? All of these questions are addressed with animations that help the students understand these basic weather concepts. The students will learn about different types of hygrometers.
