Yes, warm air expands and rises, while cold air contracts and sinks. It could happen that a low cold air stream is forced to rise when coming up against a high mountain range. Though, once over the range, the cold air tends to cling to the far side of the range as it sinks into the bottom of the valleys on the other side.
As warm air rises it becomes cooler and the relative humidity of the air mass rises. If the relative humidity exceeds 100% water precipitates out.
As cool air sinks the air mass becomes warmer and dryer.
Both these reactions relate to the relationship PV=nRT.
The warmer fluids is less dense, and also the kinetic energy of the molecules increases.
Convection current
Convection occurs.
the world becomes very hot
when warm air rises cooler air moves in to replace it
The warm air rises
it gets warmer
Colder air blowing in from the sea to the land is called a "sea breeze".
Warm air rises, and cool air sinks.
It's density decreases, so will rise (or float) above surrounding cooler air.
the warm air rises because of its Kinetic energy !
Where the air is over a parts of the Earth's Surface that is warm, the air warms. Warm air rises and as it rises it is replaced by cooler air that is sucked in from parts of the Earth's surface which are comparatively cooler. This movement causes a cyclic circulation of the air called win and weather.

Warm air close to the ground rises and becomes cooler.
when warm air rises cooler air moves in to replace it
it gets warmer as it rises
The air expands as it is heated this is due to the increased activity of the molecules composing the air. It also rises as its density is reduced compared to the cooler air in the room. The pressure of the warm air remains the same as that of the cooler air.
It gets warmer.
The geosphere will warm the atmosphere.
Warm air above the land rises and is replaced by cooler air from the water, causing a convection current. Just got this from apex!
The warm air rises
