Key Terms Defined
- Convection current
- Air or liquid moving from place to place while carrying heat
When the air inside the balloon is heated, the molecules in the air begin to move around and spread out, and the air becomes less dense. The surrounding, colder air falls beneath the hot air. This forces the warm air upward, which pushes the balloon up with it. The moving warm air creates a convection current.
