Cold air is compact air Hot air is less dense than cold air Ergo, hot air rises ; cold air sinks
Convection...
Heat rises, whereas cold air sinks.
When cold air sinks to the ground The sun heat it again when the air gets hotter it will rise. The movement of this air is what we feel as wind.
Because cold air is denser than warm air, so warm air floats way up to the sky or to your ceiling, while cold air sinks to the ground. That is why the floor is always cold, and attics are always hot.
Fog appears when cold air sinks to the ground.
Cold air sinks.
it is heated by the ground , and becomes less dense and rises i found that in my science book I'm in 6th grade
technically hot air does not really rise it is the cold air that sinks below it because it is more dense.
cold air.
At the poles, cold air sinks. Simple
Warm air rises and cold air sinks. This is called convection and happens because warm air is less dense and lighter.
Warm air rises at the equator and cold air sinks at the poles. Warm air expands and cool air contracts and compresses.
Warm air rises,and then sinks when the air is cold.
warm air rises cold air goes down sinks
Warm air rises. Cold air sinks.
Warm air molecules are fast moving and therefore less dense than cold air molecules. Since cold air is more dense (more slowly moving) it sinks.
