Warm air close to the ground rises and becomes cooler.
Cold air is denser than warm air, so it sinks below warm air due to gravity. This sinking motion causes cold air to flow under warm air, leading to the familiar pattern of cold air near the ground and warm air above it.
When warm air contacts cold air, the warm air typically rises above the cold air. This occurs because warm air is less dense than cold air. As the warm air rises, it can lead to the formation of clouds and precipitation, depending on the moisture content and other atmospheric conditions.
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.
The cold air pushes under the warm air.
Warm air rises above cold air because it is less dense than cold air. As warm air absorbs heat, its molecules gain energy and spread out, causing it to become lighter and rise. This creates convection currents, with warm air moving upward and cold air sinking to take its place.
Cold air is denser than warm air. Which allows it to slide under that warm air and displace it.
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.
No, a warm front forms when a warm air mass advances and overtakes a retreating cold air mass. As the warm air rises over the cold air, it cools and condenses, creating precipitation and leading to a gradual warm-up in temperature.
Cold air is denser thus heavier.
A cold air mass comes in under a warm air mass.

Cold air is more dense than warm air and therefore heavier
