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.
In a convection current, warm fluid rises due to its lower density and is replaced by cooler fluid. As the warm fluid rises, it transfers heat to the cooler surroundings, leading to circulation and the formation of a convection current.
When warm air rises and is replaced by cooler air, it creates convection currents. These currents are responsible for moving heat energy throughout the atmosphere and can lead to various weather phenomena, such as clouds, rain, and wind.
when warm air rises cooler air moves in to replace it
decreases as it becomes less dense and expands. This is why warm water rises in cooler water.
it gets warmer

It's density decreases, so will rise (or float) above surrounding cooler air.
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 water is less dense than cooler water, causing it to rise. As warm water rises, it displaces the cooler, denser water below it. This process is known as convection and is a natural mechanism for heat transfer in fluids.
the warm air rises because of its Kinetic energy !
Warm air close to the ground rises and becomes cooler.
it gets warmer as it rises
when warm air rises cooler air moves in to replace it
The geosphere will warm the atmosphere.
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.
decreases as it becomes less dense and expands. This is why warm water rises in cooler water.
