4. Greenhouse Effect
Energy from the Sun (Visible light) is Absorbed by the ground, reradiated to atm. by conduction and convection (heat).
Greenhouse Gases(CO², Methane, water vapor) trap in the heat. Waves to big to escape.
(Think of a car)

5. 6 Factors that Affect Climate
#1 Latitude
Latitude increases, Temperature decreases
Rays become less direct, temperatures cooler

6. #2 Altitude As your altitude increases temperature decreases.
Think snow on mountains

7. #3 Planetary Winds At 0 & 60 degrees Lat
Low Pressure Conditions Wet Warm
At 30 & 60 degrees Lat
High Pressure Conditions Cool Clear

8. #4 Mountain Ranges Windward Side Air rises cools and Rain.
Leeward Side Air sinks Warms and Becomes Dryer.

9. #5 Coastal-vs-Inland Climates
Water has a Higher Specific Heat so has moderate temperatures.
Coastal Areas have a smaller range of temp. throughout Year
Inland Areas have hotter summers & Colder winters. More Range.

10. #6 Ocean Currents Brings Cold Water to Warm Areas
Brings Warm water to Cold Areas
