What happens when air is heated?
Warm air is lighter than cold air, and so when air is heated it rises. Colder air then rushes in at ground level to take its place. On a small scale, this effect can be seen when the Sun heats up a field and the air above it rises in a thermal; you can often see birds like eagles soaring on these air currents.
Birds can soar upwards on columns of warm, rising air, called thermals.
