Unformatted text preview: earth is curved, spread energy over area poles get little energy Oblique rays give less energy than direct> due to curved earth. #3 Break down the earth into bands. Equator? High Temperature, High evaporation rates, Low pressure, air rises = HIGH precipitation (convection) 20-30 degrees? Sub Tropical High Pressure belts > sinking dry air > LOW precipitation Middle Latitude? clashing colder dryer air from polar regions> warmer moister air from the tropics- moderate amounts of frontal precipitation Polar Regions? Low Temperatures, Low Evaporation, High Pressure, air sinking= LOW precipitation...
