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 currents are movements in (and of) the liquid part of our earth due to differences in temperature. The warm rises and the cool sinks. But the cool which has sank will be heated (the heater, the core, is at the bottom) and the warm, which has risen, will be cooled.
