Final answer:

Convection currents form due to differences in density causing warm air to rise and cold air to sink.


Explanation:

Convection currents form when warm air rises and cold air sinks due to a difference in density. Warm air is less dense, so it rises, while cold air, being denser, sinks. This process of warm air rising and cold air sinking is driven by buoyant forces.
