Review of Atmosphere and Geochemical Cycles
Air Has mass and volume
Composition Nitrogen – inert Oxygen – reactive Others are CO2 and H2O
Gravity, Density and Atmospheric Pressure
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)
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.
