1. Land Breezes and Sea Breezes Sea Breeze

2. Raditon
When we think of air it is often hot closer to the earths surface. This is because the radiation from the sub hits the land is absorbed by it and that energy takes the form of heat.
The air touching the surface of the Earth is then heated by Conduction

3. Convection
Remember that we have learned the transfer of heat By convetion is:
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat
Carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises

4. Air Movement
This heating of air through Radiation, Conduction and Convection creates the expanding and moving of air.
Hot air rise because it is less dense then cold air. As hot air rises cold air needs to move in to takes its place.
This is what creates wind.
