Cool enough to increase in density and sink.
The core of the earth contains radioactive material and this causes a convection current in the mantle.
When a material becomes hot enough, it rises because it less dense.
Convection currents in the earth originate in the mantle. The liquid moves in a circle pattern as the hotter magma rises and the cooler magma falls. This can also be observed in any fluid material, gases or liquids.
a convection current occurs when a potato picked by a farmer falls off the wagon and is eaten by a donkey ps: your welcome
In a convection current, heat flows with the heated molecules as they move around in the liquid or gas. In a solid, the heat transfers via condition
the convection currents will stop

warmer material will move upward were it cools then fall back to the bottom so it can start the cycle (convection current) once again
the convection currents will stop
... move to the bottom of the fluid

He won't complete many push-ups on that hot deck due to a little thing I like to call "the convection current effect".

Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.
