Q. What is the basis for the formation of winds due to heating of different areas on Earth ?

1. The air in cold temperature regions gets cooled, expands and becomes more dense and rises up. It's place is taken by heavier air from adjacent regions.
2. The air in cold temperature regions gets cooled up, expands and becomes less dense and rises up. It's place is taken by heavier air from adjacent regions.
3. The air in high temperature regions gets heated up, contracts and becomes more dense and rises up. It's place is taken by heavier air from adjacent regions.
4. The air in high temperature regions gets heated up, expands and becomes less dense and rises up. It's place is taken by heavier air from adjacent regions.
