Convection Currents
The mantle is made of much denser, thicker material, because of this the plates "float" on it like oil floats on water.
Many geologists believe that the mantle "flows" because of convection currents. Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over. The next time you heat anything like soup or pudding in a pan you can watch the convection currents move in the liquid. When the convection currents flow in the mantle they also move the crust. The crust gets a free ride with these currents. A conveyor belt in a factory moves boxess like the convection currents in the mantle moves the plates of the Earth.
Convection currents are caused by the inner core, which is the Inner layer of the Earth.
Convection currents begin due to the extreme heat of the inner core. The inner core heats up the very bottom of the mantle. The heated up substances within the mantle has a higher temperature than those higher in the mantle and closer to the surface of the earth. The particles of the heated substances spread out because they are moving more quickly, and they become less dense and rise to the top of the mantle, pushing the cooler substances down towards the bottom of the mantle. Thus, the process of convection continues.
Convection currents are caused by the heat from the inner core. A layer in the mantle, called the asthenosphere, is fluid-like and is heated by the core, thus inducing convection currents to form.
Earths outer core.
The heat from the gradual decay of long lived radioisotopes creates areas of upwelling within the mantle material. The material that rises causes adjacent material to descend to fill the void. This motion occurs over very broad areas, and is what drives sea floor spreading and plate tectonics. It all boils down to nuclear decay.
The cooling of the Earth's interior.
Convection in the earth's mantle.
Earth's rotation causes mantle convention. But you already knew that! :P
Simple- Convection in the mantle causes mantle to slowly move, and it pushes against the crust. As it does this, the tectonic plates move.
Convection currents in the mantle are what causes tectonic plates to move. Uneven heating of the mantle results from radioactive decay of some long-lived isotopes in the mantle, which are not evenly distributed.

Heat from the core and the mantle itself causes convection currents in earth's mantle.
No. Earth's crust does not convect. Convection in the mantle, however can create hot spots and rifting, which can lead tot he formation of volcanoes.
the convection currents will stop
convection currents in the upper mantle
QuestionThe term for the circular movement of material inside earth's mantle is convection current. This current causes the movement of the tectonic plates.
It's called the convection current.
