air balloon

Floating heated sphere

An air balloon is a balloon that rises because it contains air heated to be lighter than the surrounding atmosphere, or more broadly, any large balloon designed for flight.

The term often appears in hot air balloon, describing the familiar craft with a basket suspended beneath a fabric envelope: We watched the air balloons drift over the valley at sunrise.
