cold air because we didn't have any sun hitting down on us. we did when the asteroid hit the earth.
Warm air is lighter then cold air. So the cold air sinks and the warm air raise.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
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.
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.
warm air and cold air are both different pressures and density's!!!!
When warm air pushes into cold air the result is a warm front.
When a warm air mass pushes against a cold air mass, it can form a warm front. This is characterized by the warm air rising over the denser cold air, leading to a gradual transition in weather conditions as the warm air replaces the cold air.
Cold air is more dense than warm air.
warm air rises cold air goes down sinks
When warm air approaches cold air, the cold air becomes denser and sinks beneath the warm air. This can create atmospheric instability and lead to the formation of weather phenomena such as cold fronts, 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 heavier than warm air because cold air has higher density. This is because the molecules in cold air are closer together, leading to a greater mass per unit volume compared to warm air.
