We had a guest speaker, Pat Spoden, who talked to us about weather. He told us some interesting facts, such as the earth is tilted on an angle of 23 degrees and that land heats faster than water. He also told us that changing temperatures create weather. One of the things I liked that he talked about is high and low pressures. High pressure means clear skies and low pressure means cloudy skies. Another cool fact he told us was that fog is basically low clouds. One of the biggest words he used was evapotranspiration and this process is greatest during the day. The last cool fact he told our class was that one acre of corn looses 400,000 gallons of water in one growing season.
