At the boundary lines of air masses with different densities and/or temperature. There are cold fronts, warm fronts and occluded fronts. Cold fronts usually move faster than warm fronts.
It depends on if you mean heavy rain or light rain. If you mean heavy rain then when a cold air mass rises over a warm air mas. If you mean light rain then when a warm air mass rises over a warm air mass.
A stationery front. A cold front is where cold air gains over warm air. Warm front is where warm air gains over cold air. An Occluded front is where warm air is pushed up and cold aair over takes at lower levels.
That depends. If the cold air pushes into the warm air, moving it out of the way it is called a cold front. If the cold air retreats with warm air coming in to to replace it, the front is a warm front. if the two air masses come together along a boundary that does not move the result is a stationary front.
They form from behind the moving cold front because the warm air condenses quickly producing clouds, rain, and stormy weather.
cold air mass & clearing conditions.
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.

This causes the cool air to pass over the top of the cold air. Occluded front is forms when a warm air mass is caught between two cooler air masses.The warm air mass is cut off, occluded , from the ground.The occluded warm front may cause clouds and precipitation.

When warm air pushes into cold air the result is a warm front.
1) Warm front - warm air mass replacing a cold air mass at ground level. Typically shifts wind southeasterly to southwesterly. 2) Cold front - Cold air replacing warm air at ground level. Tyoically shifts southwesterly to northwesterly 3) Stationary front - Equal amount of energy between warm and cold air masses creating a "stalemate".
A stationery front. A cold front is where cold air gains over warm air. Warm front is where warm air gains over cold air. An Occluded front is where warm air is pushed up and cold aair over takes at lower levels.
When a warm front passes it leaves behind hotter tempatures and more humidity, it is replacing the cold air with warm air basically.
That depends. If the cold air pushes into the warm air, moving it out of the way it is called a cold front. If the cold air retreats with warm air coming in to to replace it, the front is a warm front. if the two air masses come together along a boundary that does not move the result is a stationary front.

Cold air is denser than warm air. Which allows it to slide under that warm air and displace it.
