1. What happens to solar energy as it enters the atmosphere?
Atmospheric Heating
What happens to solar energy as it enters the atmosphere?

2. Three types of heat transfer
Radiation
Conduction
Convection

3. Radiation-energy transferred by waves
This is how Earth receives energy
Electromagnetic waves
Earth only receives a fraction of the amount of energy sun radiates
Drives the weather cycle

4. Conduction-energy transferred by contact (must touch)
Experience this when you touch something hot
Thermal conduction is when heat energy is passed through material
Always transferred from warm to cold in thermal conduction
When air molecules come into direct contact with the warm surface of Earth, thermal energy is transferred to atmosphere.

5. Convection-energy transferred by circulation of a liquid or gas
Transfer of thermal energy by circulation or movement of a liquid or gas.
Most thermal energy in the atmosphere is transferred by convection.
Air is heated, condenses, then rises. Cycle repeats
Cool air sinks, pushes warm air up (heat rises, remember), cool air is heated by earth’s surface and begins to rise again.
The circular movement of air is called a convection current
