1. Air molecules travel from areas of high pressure (density) to areas of low density.
WHY??? Because crowded (High pressure) molecules want to spread out

2. H L

3. Which means air molecules travel from areas of cold air (H) to areas of warm air (L).
WHY??? Because cold molecules are condensed and want to spread out.

4. When we pulled the book back we created a low pressure:

5. The path from High Pressure to Low Pressure is not necessarily straight!

6. Wind travels clockwise around a high pressure and counterclockwise around a low.

7. Wind travels clockwise around a high pressure and counterclockwise around a low.

8. The flow of H to L is most evident in land and sea breezes.
A Convection Current is this
Natural flow from High to Low.

9. During the day, the beach gets hot (making low pressure) and
The heat rises. The air over the water is cooler and creates
A high pressure. The cool air of the ocean replaces the warm air over the land in what is called a Sea Breeze.

10. During the night, the beach gets cold (making high pressure) and the cool air falls. The air over the water is warmer and creates a low pressure. The warm air of the ocean replaces the cool air over the land in what is called a Land Breeze.

13. South when looking at a globe.
Next, the air not only rises and falls vertically in the atmosphere, it travels to the north and
South when looking at a globe.

15. The movement of air is made complex in many ways
The movement of air is made complex in many ways. First, the earth is spinning (rotating)!

16. Try walking on a turn table…
Try walking on a turn table…. That’s what the coriolis effect causes on Earth.
