Day to day variations › Temperature › Cloud cover › Precipitation › Humidity
Long term weather › Annual temperature › Annual precipitation › Average yearly snow pack › Desert climate, rainforest, etc.
Radiation Convection Conduction
transfer of energy by electromagnetic waves. Can carry energy through space (does not need matter)
Poles & equator receive the same amount of solar energy Equator: direct, high angle (90 degrees), high intensity solar energy Poles: indirect, low angle (30 degrees) solar energy › Solar energy spread out over a larger area
Intense heat at the equator is distributed around the world › Movement of air & water Heat imbalance wind (cause) (effect)
Caused by rotation of Earth Causes water & air to curve N Hemisphere clockwise
Light Energy Chemical Energy › Photosynthesis (by plants) › Chemical energy Stored energy Sugar
Chemical energy Mechanical & Heat energy › Respiration (every cell does this) › Mechanical energy: movement
1. Solar 2. Chemical 3. Mechanical & heat
Greenhouse Effect › Natural warming › Atmosphere traps the heat (blanket) › No greenhouse effect on Earth it would be too cold for life (all water frozen) Global Warming › Increasing concentrations of CO2 (GHG, traps in more heat) › Increasing temperatures
Absorb › Waves taken in › Changed into heat Reflect › Waves bounce off an object › Are NOT changed into heat
