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.
Convection current is the flow of hot fluid in a circular pattern. A convection current is a form of transfer of energy. It occurs mainly in liquids, but it can also occur in â¦ gases. In a convection current, the particles with greater energy (the particles that are hotter) rise because they become less dense.
