Cold air is more dense than warm air. If flows beneath the warm air and forces it to rise.
When air warms up, it expands a little, and so it becomes less dense. Density is the ratio of mass to volume. Within a fixed volume, there will be less mass (less air) in a sample of warmer air than there will be in a sample of cooler air. The less dense air floats above the cooler air. This is why hot air balloons will rise.

What is the precipitation at a cold front like?
A cold front brings in cold air. The cold air causes warm air to rise quickly. The rising air forms cumulus clouds. There is often heavy precipitation at a cold front.
How does an occluded front devolope?
When a depression (or a low pressure system) forms, it usually consists of a warm front and a faster moving cold front. To the north of the warm front is the cool air that was in the area before the depression developed. As the depression intensifies, the cold front catches the warm front. The line where the two fronts meet is called an occluded front. When an occluded front passed overhead, you feel changes in temperature and wind speed. A cold occlusion occurs when the air behind the occluded front is colder than the air ahead of it. The cold occlusion acts in a similar way to a cold front in that the the cold air behind the front undercuts the cool air ahead of it. The other type of occluded front is the warm occlusion. A warm occlusion occurs when the air behind the occluded front is warmer than the air ahead of it. The warm occlusion acts in a similar way to a warm front in that the cool air behind the front is lighter than the cold air ahead of the front. This causes the cool air to pass over the top of the cold air.
What type of front typically produces the fastest rise of air?
cold front
What type of front forms from cold air move underneath warm air forcing the warm air to rise?
This is a cold front.
Air mass that forms over a cold region is called?
Air masses that are cold and forms over polar regions is polar. A cold front occurs when a cold air mass meets and displaces a warm air mass. A front that forms when a warm air mass is trapped between cold air masses and forced to rise is called a occluded front.

What are the four types of fronts?
Cold Front-When a fast moving cold air mass runs into a slowly moving warm air mass Warm Front-A fast moving warm air mass collides with a slow moving cold air mass Stationary Front-When a cold and a warm air mass meet, but neither one has enough force to move the other Occluded Front-When a warm air was is caught between two cold air masses
As a cold front passes barometric pressure should?
It will rise after the front passes.
What type of front typically produces the fastest rise of air?
cold front
What causes weather conditions to change along front?
when fronts meet, the cold air undercuts the warm air to rise and create tornadoes, associated with rain.
What type of front forms from cold air move underneath warm air forcing the warm air to rise?
This is a cold front.
What are the properties of a warm front?
It separates warm from cold air ahead. In other words, it overruns the cold air mass. A cold front on the other hand will under-cut the warm air mass.So, the properties of a warm front when it is passing is warming (obviously) then light showers. the visibility will be poor but the dew point will be steady.Pressure should be leveling off.After it passes the dew point should rise then become steady.Pressure should rise then decrease.There is usually no precipitation, but sometimes you can also have light rain.
What happens after a occluded front?
After an occluded front passes temperatures drop if it was a cold front, and rise if it was a warm front. Pressure rises, and there is light-to-moderate precipitation, followed by clearing. Visibility improves and there is a slight drop in the dew-point if it is a cold-occluded front and a slight rise if a warm-occluded front.
What is a front that forms when a warm air mass is trapped between cold air masses and is forced to rise?
Occluded front
A front that forms when a warm air mass is trapped between cold air masses and is forced to rise?
occluded front is what it maybe!
What happens to the warm air when it overtakes the cold air?
the warm air will rise
