Warm air rises. Cold air sinks.
Air is most likely to rise after a warm front passes over an area. Air rises as it gets warmer.
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.
the hot and dry air mass are most likely to rise
Heat can cause air to rise :)
The hot and dry air mass is most likely to move in the direction where lower pressure systems exist. This typically means that it will move towards areas with cooler temperatures or where moist air masses are located.
Farts rise in the air because they are lighter than the surrounding air.
A warmer world is least likely to result in lower energy consumption. Increased temperatures may lead to more frequent use of air conditioning, causing energy usage to potentially rise.
Buoyant air will rise until it reaches warmer air that is the same density as itself.
It is the warm air
When air is heated, it will expand and become less dense. This causes it to rise, creating convection currents. As the heated air rises, cooler air will flow in to replace it, leading to changes in temperature and pressure in the surrounding environment.
Air pressure would most likely decrease ahead of an approaching storm system. This drop in pressure is due to the arrival of low pressure associated with the storm, which causes the air to rise and the pressure to fall.
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
