The air moves accordingly due to the change in the the density and the convection
Explanation:
- The cool air enters the the tower from the bottom of the tower. However as it moves up the tower there is heating up of the air.
- There is a decrease in the the air density when it is heated. as a result of this ,less denser substance moves UP.
- Due to constant heating of the air , expansion of the air and decrease in density takes place because of which the constant upward movement of the air is continued.
