  1. Composition of the Atmosphere 78% - Nitrogen 21% - Oxygen 1% - Argon, CO2, etc. Chapter 17The Atmosphere

  2. Evaporation & transpiration Condensation  precipitation Water is neither created nor destroyed Water Cycle

  3. Photosynthesis Respiration Plants! Take in CO2, Water and sunlight to release O2 Mammals!Take in O2, water and food to release CO2

  4. Conduction Convection Radiation Direct contact Currents Transfer of heat through visible light (SUN!!!) 17.2 Movement of Heat in the Atmosphere

  5. Temperature The measure of HEAT in the atmosphere

  6. Troposphere Stratosphere Mesosphere Thermosphere CFC’s are chlorofluorocarbons that EAT ozone! Where all weather occurs; where we live O3….Ozone layer (protects us from UV light) CFC’s destroy Ozone! 3rd layer Magnetic field (ionosphere) – Auroras! Structure of the Atmosphere

  7. Insolation Intensity of insolation Incoming Solar radiation Higher angles received less direct sunlgiht That is why the poles are cold and the equator is always so warm Temperature Variations

  8. Time of Day….. What is the warmest time of day??? What is the coldest time of day?? Takes a while for the earth to heat up and cool down every day 3pm 3am

  9. Latitude…. Higher latitudes tend to be colder b/c they have less direct sunlight Closer to the equator tends to be warmer b/c there is more direct sunlight all year long

  10. Time of year….. Tilt of the earth………….. Tilted away from the earth means less direct sunlight - colder

  11. Cloud cover……… Clouds block the sun ……temperature is cooler

  12. Land heats up and cools down FASTER than water. WHY!???? Land is a solid!! Therefore water heats up and cools down SLOWER because it is a liquid. That is why the oceans are warmest in the fall and coldest in the spring HEATING OF LAND AND WATER
