Warmer particles are moving faster and less dense (this is why hot air balloons float) then colder particles and rise.
For this reason magma in the Earth is bouyant (Floats) compared to the cooler rock and tends to rise to the surface.
A great example of this effect is a Lava Lamp. The wax near the light at the bottom becomes hot and rises. As it cools it sinks back down.
Most materials tend to go from:
Ironically ancient civilizations may have already known these 4 states in the form of Earth (Solid), Water (Liquid), Wind (Gas), Fire (Plasma) well over 3000 years ago.
It does not.
Take a volume of air at any given temperature.
If you warm that air, the volume will expand (the air becomes less dense).
If you cool that air, the volume will shrink (the air becomes more dense).
Less dense things float on denser things. Thus where air is warmer than surrounding air (like above a heating radiator) it will rise up.
More dense things sink in less dense things. Thus where air is cooler than surrounding air (like when you open the door of the refrigerator) the cold air will fall out.
From this you will understand that while warm air rises, cold air sinks (not rises as you imply in your question).
warm air is lighter than cold air because the warm air molecules move around faster than cold air molecules
Because hot air is lighter than cold air.
Well, warm air rises and cool air sinks! Your welcome! :) <3
the warm air will rise
Stratus and nimbostratus clouds are found where warm and humid air is lifted over cooler air ahead of a front.
When air is reduced to the dew point temperature and is near the ground, a fog is formed. It is a form of a stratus cloud.
When air of different temperature collides, the result is usually rainfall and sometimes a storm. A warm front is created when warm air meets cold air, and the warm air starts to rise over the cold air. As warm air rises, it begins to cool, and condensation occurs, resulting in rain clouds. When cold air moves towards warm air, the cold air moves underneath the warm, forcing it to rise very quickly (more quickly than a warm air front will rise). Because of the rapid rise of the warm air, it means it cools down more quickly, and the resultant rain clouds may turn into a storm.

The cool air will sink and the warm air will rise.
It's density decreases, so will rise (or float) above surrounding cooler air.
Convection currents in the air cause winds to form. As warm air rises, cooler air rushes in to fill its space near the ground. The rising warm air becomes cooler and begins to fall. The cooler air near the ground becomes warmer and begins to rise.
This is called a warm front or rise.
a warm front
When warm moist air from the gulf or anywhere else meets cooler air over Florida or anywhere else, it rains. Lightning and Thunder frequently accompany such a meeting.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Hot air is less dense than cooler air, therefore the balloon will rise (float) on the cooler air around it.
True. Cool air sinks and warm air rises.
Air is most likely to rise after a warm front passes over an area. Air rises as it gets warmer.
Well, warm air rises and cool air sinks! Your welcome! :) <3
