Convection currents are the transfer of heat through the Earth's magma. They can be found in the mantle. The hottest part of the Earth is the core. the heat from the core is transferred into the lower mantle.
The particles in fluids (liquids or gases) can move from place to place when heated. Convection occurs when particles with a lot of heat energy move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection.
