Answer:

Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. ... Convection currents within the earth move layers of magma, and convection in the ocean creates currents...

EXAMPLE

Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. ... Ice melting - Heat moves to the ice from the air. This causes the melting from a solid to liquid. Hot air balloon - A heater inside the balloon heats the air and so the air moves upward.
