1. Review of Atmosphere and Geochemical Cycles

2. Air Has mass and volume

3. Composition Nitrogen – inert Oxygen – reactive Others are CO2 and H2O

4. Gravity, Density and Atmospheric Pressure

5. Modes of Heat Transfer Radiation-heat energy in transit as electromagnetic radiation Convection-involves fluid currents that carry heat from one place to another Conduction-energy is transferred from a high temperature region to low temperature region due to random molecular motion (diffusion)

6. Radiant Energy Electromagnetic energy that travels in transverse waves. Radiant energy includes visible light, x-rays, gamma rays and radio waves. Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on Earth possible.

7. Greenhouse Effect
