Geography
  1. Physical Environments
    1. Weather
      1. Factors Affecting
        1. Latitude
          1. Closer to poles = Colder
            1. More sky for sun to go through t/f more energy absorbed by sky, not land.
              1. Energy is spread over a larger area b/c earth curvature t/f less energy per square metre.
                1. Albedo Effect
                  1. Ice/snow reflects energy
                    1. Up to 90% lost
                  2. Earth's Tilt
                    1. Poles get 6 months sun p.a, w/a Equator gets 12 months sun p.a.
                2. Altitude/Relief
                  1. Temperature
                    1. -1K/100m
                    2. Precipitation
                      1. A Cross Section of the UK
                        1. East of UK is drier than west b/c of rain shadow.
                          1. Orographic Precipitation = Relief Rainfall
                    3. Aspect
                      1. North facing slopes = colder
                        1. Receives less energy
                          1. North facing Ski Slopes

                        1. Sea = "big-ass temperature controller"
                          1. Regulates extremes of winter and summer
                            1. Water has higher heat capacity than air
                          2. Currents
