Answer:
Point A
Explanation:
The Northern Hemisphere is furthest away from the sun in position A. Therefore the sunlight takes longer to reach the Earth which results in the Northern Hemisphere experiencing winter.
Hot/ warm air is less dense than cold/cool air. Therefore warm/ hot air rises and cool/cold air falls in the atmosphere to create convection currents. The hot air balloon also uses this concept to fly. The air in the balloon is heated by the inbuilt flamer and when the air rises in temperatures (in comparison to ambient air temperatures) it becomes less dense and begins to rise. This raises the balloon into the atmosphere.
