What is less dense warm air or cold air?
Warm air is less dense than cold air because its molecules are more spread out due to their increased energy and movement. This causes warm air to rise, as it is lighter than the denser cold air.
When cold air moves toward warm air it pushes the warm air where?
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.
