Greenhouse Effect - animated diagram

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)

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

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

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

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

#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.

#6 Ocean Currents Brings Cold Water to Warm Areas Brings Warm water to Cold Areas Refer to Reference Tables
