1. The Atmosphere

2.  Nitrogen (78%)  Oxygen (21%)  Water Vapor (less than 4%)  Carbon Dioxide (less than 1%)  Methane (less than 1%)  Nitrous Oxide (less than 1%)  Ozone (less than 1%) Compounds

4. Weather is caused by the movement or transfer of heat energy.  Radiation: the flow of electromagnetic radiation (Earth receives solar energy this way).  Conduction: energy transferred by collisions that take place between heat-carrying molecules.  Convection: involves the movement of warmer air molecules to cooler areas.

5.  Air mass  Air Pressure  Albedo: reflectivity Low: ocean water Moderate: land masses High: snow and ice  Altitude  Angle of Sunlight Factors that Influence Climate

7.  Carbon Cycle: the consumption of carbon results in cooling  Clouds  Distance to oceans  Fronts  Greenhouse Effect  Heat (Convection)  Land Changes: urbanization and deforestation

8.  Landmass Distribution  Latitude  Location  Humidity  Mountain Ranges  Plate Tectonics  Volcanoes  Pollution  Precession  Rotation

9.  Solar Output  Wind Patterns  Human Activity: deforestation, urbanization, etc. Factors (Video): http://www.youtube.com/watch?v=TWB2OHk ooPI Human Activity: http://oceanservice.noaa.gov/education/pd/cli mate/factsheets/howhuman.pdf
