It happens in the mantle. The middle layer of the Earth. The mantle's fluid or magma rises from the Earth's core. It becomes less dense. It travels away from the core cause of the tremendous heat and pressure. Once it cools off it cones back down. When it starts to heat back up again then it rises back up. It goes in a circular motion. That's convection current.
causes warm air to rise and sink
you should know this

Geologists believe that covection currents are what causes continental drift. If covection currents never happened and their force didnt move the continents then we'd all live on one large super continent.
Conduction, convection ,radiations are three methods of heat transfer. Conduction is carried out by direct contact with materials covection & radiation are carried out without any contact with the material
Convection currents are caused by differences in density. Warmer fluid is less dense, so a fixed volume of the warmer fluid is lighter. Colder fluid is denser, and so heavier in a fixed volume. The colder, denser fluid presses down and falls below the less dense fluid, which floats up to the top of the fluid. Often, there is a heat source that the bottom of the container, so the fluid at the bottom, which was more dense, warms up and becomes less dense. At the same time, the fluid at the top cools down and becomes more dense, and so the cycle repeats, forming a convection current.

I need to know the same thing
um it is the covection moving

The major ones involve the mantle and the oceanic crust.
Insulation is not a method of heat transfer.
Most likely Convection!
