Presentation transcript:

 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
