Air that has been heated has molecules that are more energetic, and this activity increase the spaces between molecules. The result is that a volume of heated air has fewer molecules than cooler air, and is displaced by the denser (heavier) cool air. It rises until it reaches the level in the atomosphere with the same density, or until it loses its heat to surrounding air. This cyclic heating and cooling creates air convection.
In the atmosphere, denser high-pressure air masses (usually cooler) will displace warmer air masses as they move across the surface. Warmer, more humid air is pushed upward along the boundaries of cooler, drier air, which produces weather fronts.

Why does warm air move upward in the thunderstorms?
Air moves up in a thunderstorm because it is wamer and therefore less dense than the surrounding air.
The upward movement of warm air and the downward movement of cool air form?
The upward movement of warm air and the downward movement of cold air forms fluids.
The upward movement of warm air is called?
Updraft
The upward movement of warm air and the downward movement of cool air form what?
Convection
What is the upward movement of warm air and the downward movement of cool air called?
Convection
When warm air move upward energy is move by?
Temperature
What process causes the warm air to move upward over the land during the day?

What is an upward flow of air?
An upward flow of (warm) air is known as a Thermal .
Why does warm air move upward in the thunderstorms?
Air moves up in a thunderstorm because it is wamer and therefore less dense than the surrounding air.
When warm air moves upward in a thunderhead it creates a zone of what?
warm air
The upward movement of warm air and the downward movement of cool air form?
The upward movement of warm air and the downward movement of cold air forms fluids.
What are the results of air being forced upward?
The results of air being forced upward is rising temperature. If air is pressurized it gets warm because the particles have to move more quickly.
How does warm air moves?
it is pushed upward
Is an updraft an upward moving current of cold air?
No. An updraft (updraught) is an upward moving current of warm air.
The upward movement of warm air is called?
Updraft
What is the upward movement of warm air and the downward movement of cold air?
Conduction
How does warm air molecules move?
The molecules in warm air move faster
