Most convection currents exist in the mantle, the layer below the Earth's crust. As the semi-molten rock heats up, it rises closer to the surface, and it sinks as it cools. This is how plate tectonics works, as the crust's plates move on these currents.
Convection currents are agents of heat transfer within Earth's interior. And could also serve as mechnism for heat generation in the earth crust.

Wind and water. Air currents (wind) carry heat poleward. This is mainly heat transfer by convection. Water currents carry heat poleward. This is heat transfer by convection and conduction.
Lithosphere
they are convection currents, caused by the heating effect of the earths core
the convection currents will stop

False.
Yes there are! That's why the plates move! It's caused by convection circulating the magma in the mantle creating currents!

They will stop.

the convection currents will be set in motion because the heat from the mantle rises and causing it to change Earth's density & force of gravity
