  3. 3. Weather Factors <ul><li>Energy from the Sun evaporates water into the atmosphere where clouds form. </li></ul><ul><li>Eventually, the water falls back to earth as rain or snow. </li></ul><ul><li>The Sun does more than evaporate water. </li></ul><ul><ul><li>It is a source of heat too. </li></ul></ul><ul><ul><li>Heat from the sun is absorbed by Earth’s surface, it heats the air above. </li></ul></ul><ul><li>Weather is the result of heat and Earth’s air and water. </li></ul><ul><li>Factors that affect weather on a local scale are temperature, moisture content, air pressure and wind speed/direction at the surface as well as some high in the atmosphere. </li></ul>
  4. 4. Air Temperature <ul><li>The temperature of air influences your daily activities. </li></ul><ul><li>Air is made up of molecules that are always moving randomly, even if there's no wind! </li></ul><ul><li>Temperature is a measure of the average amount of motion of molecules. </li></ul><ul><li>When temperature is high, molecules in air move rapidly and it feels warm. </li></ul><ul><li>When temperature is low, molecules in air move less rapidly, and it feels cold. </li></ul>
  5. 5. Random Facts <ul><li>The lowest ever recorded world temperature was in Antarctica July 21,1983 at a bitter -89.6°C. </li></ul><ul><li>Libya has the highest recorded temperature on earth at a sweltering 162°F </li></ul><ul><li>WOWSERS! </li></ul>
