Convection is the movement of a physical quantity (for example heat) because of the movement of the matter.

For example, the wind is the movement of the air and it can cool down a room if the window is open because the cold air comes inside of the room. The movement of the clouds, the sea waves and many types of heaters are examples of convection.
