Cold air
the air becomes dense and it sinks
When air loses its heat it actually becomes more dense and sinks which starts a convection current
high
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
Cold air
Because hot air rises and cold air sinks. So when they heat the air in the balloon it becomes less dense or less heavy and that makes it rise ad the volume becomes more.

Yes ,because it sinks to the bottoms because it is heavy.
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.

Ice Air is less dense than water, so water sinks below air. A rock is more dense than water, so it sinks in water and air. And helium, which is less dense than air, rises in air and in water.
Argon is more dense than air.

Less dense (warm) air rises. More dense (cool) air sinks. The two put together are convection.
