convection

Warm fluid rising

Convection is heat transfer through the movement of fluid—liquid or gas.

When air or water warms, it becomes less dense and rises; cooler fluid sinks to replace it, creating a circulation pattern.

A convection oven uses fans to circulate hot air for faster, more even cooking.

Convection currents in the atmosphere drive weather patterns.
