Bitesize convection currents
WebApr 16, 2024 · What is a convection current BBC Bitesize? Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Air current close to a radiator. Heat energy is transferred from hot places to cooler places by convection.
