Question

Does cool air push warm air upward?

Answer 1

Hot air is less dense than cold air, which is why hot air rises and cold air sinks, according to the United States Department of Energy. Hot and cold air currents power the weather systems on earth. The sun plays a major role in heating the planet, which also creates hot and cold air energy systems. Warm air currents typically bring rain, because they form over oceans. That’s why hurricanes and tropical storms form at sea and eventually move toward land.

Answer 2

Cooler, denser air flows in underneath the warmer, less dense air, and pushes the warmer air upward. When this air cools, it becomes more dense than the warmer air beneath it. The cooled air sinks and moves under the warmer air.
