1. Wind The horizontal movement of air. Warm air rises and cold air sinks. Temperature Differences High and Low pressure like to balance out. Pressure Difference

2. Temperature: WARM AIR Molecules move faster. Air becomes less dense. Less dense air rises. Slow moving Very Dense Warming up Moving faster Very Warm air Moving really fast Spreading out Becoming less Dense 50° 70° 90°

3. Temperature: COLD AIR Molecules move slower. Air becomes more dense. More dense air sinks. Cooler air Slow moving Closer together Becoming more dense Cooling down Moving slower Very Warm air Moving really fast Spread out Less Dense 50° 70° 90°

4. Temperature Differences: Rising & Sinking Air

5. Pressure Differences Air Rises Low Pressure Air Sinks High Pressure

6. The Creation of Wind 1.Temperature difference = rising/sinking air. 2.Rising/sinking air = pressure difference. 3.Pressure likes to balance out = WIND !!!

7. Sea Breeze Wind blows from Sea to Land.
