warm air rises cold air goes down sinks
When cold air moves toward warm air, it pushes the warm air upward because cold air is denser and therefore heavier than warm air. This creates a lifting mechanism known as cold air advection, which can lead to the formation of clouds and precipitation.
Warm air moves over cold air and replaces it.

When warm air moves into a region occupied by cold air, the warm air will rise above the cold air due to its lower density. This results in the cold air being displaced and pushed out of the region, a process known as warm air advection. This movement can lead to changes in temperature, pressure, and weather patterns in the region.
Yes
The front you are referring to is called a cold front. Cold air is denser than warm air, so when a mass of cold air moves underneath warm, moist air, it lifts the warm air rapidly, leading to the formation of clouds and potentially precipitation.
