Heat is caused by molecules vibrating and hitting one another. The hotter the air the more the molecules vibrate and the bigger space each molecule needs. This causes the air to expand and its density to fall.
As air cools, the vibrations slow down and the molecules need less room. This causes the air to contract and its density will go up.

What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
When cold air moves toward warm air it pushes the warm air where?
It pushes the warm air above the cold air
Does cool air follow warm air or warm air follow cool air?
um i think cold air follows warm air
When a warm air mass meets a cool air mass what does the warm air mass do?
a warm front
What happens to the warm air when it overtakes the cold air?
the warm air will rise
When warm air meets cool air does the warm air sink?
The cold air pushes under the warm air.
When warm air approaches a large body of cold air what happens to the warm air?
The warm air rises
When cold air moves toward warm air it pushes the warm air?
I pushes the warm air upwards.
What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Air warm rebus?
warm air
When cold air moves toward warm air it pushes the warm air where?
It pushes the warm air above the cold air
What air mass is warm?
a warm air mass is a large body of air that is extremely warm
Does cool air follow warm air or warm air follow cool air?
um i think cold air follows warm air
What is true A warm air is less dense than cool air B warm air is as dense as cool air. C warm air has no density. D warm air is denser than cool air?
Warm air is less dense than cool air.
When a warm air mass meets a cool air mass what does the warm air mass do?
a warm front
What does warm air do?
Warm air rises,and then sinks when the air is cold.
Why doesn't a warm air mass under a cold air mass at a warm front?
Warm air is lighter than cold air, that means that warm air will rise and the cold air will sink.
