3. Forms clouds, creating condensation and releases energy

Amount of heat needed to raise temperature of a substance by 1 degree Celsius
EX: Water has a very high specific heat
1. Air rises

Cold air near the poles sinks and flows towards lower latitudes
Prevailing winds that blow from east to west between 60degrees-90degrees latitude in both hemisphere.
