It expands. What happens is that the molecules that make up air begin to vibrate as they become warmer. This increases the amount of space between each air molecule. (e.g. put your hands in the 'prayer' position out in front of you. Pretend each hand is a molecule. Look at how much space your hands are taking up. Now clap your hands (this is to mimic vibration). Now see how much space each hand (molecule) is taking up! It's a lot more). Because now there are fewer molecules within a particular area (i.e. they pushed others out from the space), the warmer air floats above cooler air because it is less dense (like wood floating on water). Hope this helps ---schpsyk---Th
This is nonsense. The movement of air is nothing to do with the VIBRATION of air molecules. Air molecules rush about in all directions. They possess kinetic energy, the energy of motion, which is the product of the mass and the SQUARE of the speed of the mass. The kinetic energy of air molecules is partly derived from the action of the sun's radiation and partly from thermodynamic and chemical processes, such as fire and the operation of internal combustion engines. The temperature of a gas is proportional to the kinetic energy PER MOLECULE. Air pressure is proportional to the kinetic energy of the air molecules PER UNIT VOLUME (known as kinetic energy DENSITY. Hence, at a given pressure, the air density decreases with temperature. The gravitational force on a volume of air (its weight) is proportional to its density. Hence, warmer air, being less dense, is displaced by the heavier cooler air which moves underneath it and the warmer air rises like a hot air balloon.

Warm air rises because of its?
the warm air rises because of its Kinetic energy !
Convection currents form when warm air rises and cold air sinks What causes the warm air to rise and the cold air to sink?
Warm air rises because it is less dense than cold air, creating an upward movement. As warm air rises, it cools down and becomes denser, then sinks back down. This cycle of warm air rising and cold air sinking creates convection currents.
When is air most likely to rise?
Air is most likely to rise when it is heated. As air becomes warmer, it becomes less dense and therefore rises. This is the principle behind the formation of clouds, thunderstorms, and other weather phenomena.
What causes the warm moist air to rise?
Warm moist air rises because it is less dense than the surrounding cool air. As the warm air rises, it expands and cools, leading to condensation and the formation of clouds and precipitation. This process is known as convection.
Does a warm front form when a cold air mass moves into a warm air mass?
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.
What does warm air do?
Warm air rises,and then sinks when the air is cold.
When air rises does it become warm?
It's the other way round - when air becomes warm, it rises.
What happens to the air in the surrounding as warm air rises?
it gets warmer as it rises
What happen to the air in the surrounding as warm air rises?
it gets warmer as it rises
What happen to air in the surroundings as warm air rises?
it gets warmer as it rises
What happened to the air in the surroundings as warm air rises?
it gets warmer as it rises
Does warm air grow warm as it rises?
Lol, no it doesn't, ..it gets colder as it rises.
Warm air rises at the equator and cold air sinks at the poles creating?
Warm air rises at the equator and cold air sinks at the poles. Warm air expands and cool air contracts and compresses.
Warm air and cold air have densities?
Yes! Warm air is less dense, which is why warm air rises. Cold air is more dense so that's why it sinks.
Does cool air sink while warm air rises?
yes the cool denser air sink while the warm less dense rises
What does warm air always do?
Warm air rises because it is less dense than cold air. This creates air currents and convection that lead to the mixing of air masses in the atmosphere.
What Moves cold air out and warm air in?
warm air rises cold air goes down sinks
