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 transfer heat from Earth's core to the mantle, causing the mantle material to flow and create movement in the lithosphere. This movement generates heat due to friction and pressure. So, convection currents help distribute heat within Earth's interior rather than produce it.
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.
It is the mantle that is inferred to have convection currents that cause tectonic plates to move. Heat from the Earth's core creates these currents, which drive the movement of the rigid plates on the Earth's surface.

False.

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

No. Convection currents are the circular motion of earth's wind. If the earth did not rotate, convection currents would not be. Does that make sense?
Yes, there are convection currents in the molten part of Earth's interior, known as the mantle. Heat from the core drives these currents, causing hot molten rock to rise, cool, and then sink back down in a continuous cycle. These convection currents play a key role in plate tectonics and the movement of Earth's crust.
