It's heavier. Warming gases makes them less dense. That is why hot air balloons work.

What atmospheric condition causes a cold front?
When colder air advances toward warm air. The cold air wedges under the warm air like a plow. As the warm is lifted it cools and water vapor condenses forming clouds
How do cold fronts form?
a cold front forms by cold air mass pushes under a warm air mass
Do convection currents push warm air down and cold air up?
Warm air naturally goes up/rises and cold air has to make a current where it can go until it reaches a warm current which is under the warm air.
Are warm fronts associated with clouds and rain?
Not Normally, usually when warm fronts heat the air up, when cold fronts come around, that is the front that normally is associated with clouds and rain. When warm and cold air collide, that's when the development of storms come around.
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
Why does the cold air normally go under the warm air?
Cold air is denser thus heavier.
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.
What are facts about cold fronts?
There is really nothing interesting about cold fronts. Cold air is overtaking warm air. Since cold air is denser than warm air, cold air goes under a warm air mass.
When warm air meets cool air does the warm air sink?
The cold air pushes under the warm air.
Why can a cold front push a warm front?
Cold air is denser than warm air. Which allows it to slide under that warm air and displace it.
What atmospheric condition causes a cold front?
When colder air advances toward warm air. The cold air wedges under the warm air like a plow. As the warm is lifted it cools and water vapor condenses forming clouds
Why does cold air tend to flow under warm air?
cold air has more water vapor so it sinks warm air does not have so much
How do cold fronts form?
a cold front forms by cold air mass pushes under a warm air mass
What is the name of the front when cold air moves under warm moist air?
Cold front.
What happen in a cold front?
A cold air mass comes in under a warm air mass.
What forms when a cold air mass moves under a warm air mass?
a cold front
What is a warm air mass advancing under a cold air mass called?
a cold front.
