Answer:
A simple example of convection currents is warm air rising toward the ceiling or attic of a house. Warm air is less dense than cool air, so it rises. Wind is an example of a convection current. Sunlight or reflected light radiates heat, setting up a temperature difference that causes the air to move.
Natural convection is a type of flow, of motion of a liquid such as water or a gas such as air, in which the fluid motion is not generated by any external source (like a pump, fan, suction device, etc.) but by some parts of the fluid being heavier than other parts. ... This creates circulating flow: convection.
