Example - amount of rainfall, solar radiation, average temperature

4. Air Masses Continental - dry Maritime - humid Tropical - warm
Polar - cold

5. Fronts Where two air masses meet and do not mix Cold Warm
Stationary - stand still
Occluded - trapped air

6. Water Cycle
Evaporation —> Condensation —> Precipitation

7. Isolines Show air pressure or temperature
As altitude increases, air pressure decreases
