Heat can cause air to rise :)
Farts rise in the air because they are lighter than the surrounding air.
Buoyant air will rise until it reaches warmer air that is the same density as itself.
It is the warm air
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
Air in a low pressure region tends to rise. This is because in a low pressure system, the air is less dense and lighter compared to the surrounding air, causing it to be buoyant and rise. This rising air can lead to the formation of clouds and precipitation.
Smells rise in the air because they are made up of tiny particles that are lighter than the surrounding air.
Warm air will rise.
air currents
expand, causing the air to become less dense and rise.
The heating of the air through the use of a burner is what makes balloons rise.
Air pressure begins to rise in a situation where there is a change in the temperature, especially when there is cold air hitting the ground. The rise in air pressure produces winds and different types of weather.
