Weather homework?

Question

Lift is a process of what.

A. Cool Air

B.Warw air

C. Requires convecte Heating.

D. Requires dry air.

Answer 1

"C" would be the best answer, in that by definition convection is air that is rising, which is a form of lift.  Cool air, warm air and dry air do not in themselves indicate lift.  But then again, you can get lift without convective heating, but it is the usual mechanism.

Answer 2

b.warm air
