The correct answer is...
Convection and the release of heat from the Earth's core drives further convection in the mantle. Convection in the mantle drives plate tectonic motion of the sea floor and continents.
Also, you may want to know....
Because the Earth's magnetic field arises in the unstable patterns of fluid flow in the core, it changes direction an irregular intervals. In recent geologic history it may have switched direction about every 200,000 years. Any kind of geologic deposit put down over time will thus have different layers magnetized in opposing directions, recording the magnetic field as it was when the layer solidified.

∙ 13y agothe mantle and crust move because the magma under the surface is heated by the core and rises to the surface, cools as it reaches the surface then sinks again to be re-warmed. this happens over and over again creating a cycle and moves the plates because of the movment.

What is subtuction?
the movement of rocks and mantle beneath the earth crust
What is caused by the movement of the plates?
The movement of the hot mantle has broken the crust apart into large plates.
Does an earthquake occur only in continental crust?
No, earthquakes can occur anywhere in the crust, oceanic crust or continental crust. An earthquake occurs when the hard brittle solid material of the crust fractures under stress. Earthquakes cannot occur deeper than the crust (the mantle is plastic and flows slowly under stress instead of fracturing, the outer core is liquid and flows even easier than the mantle).
Is the crust a convection?
No. The crust is too rigid to convect. The mantle convects, and this convection is part of what controls the movement of tectonic plates.
How is heat transfer in the earths mantle related to the movement of the earths crust?
The heat transfer is moved to the crust. The earth's crust moves to the inner core
What feature of the mantle allows movement of the earths crust occur?
The much of the mantle is solid but ductile. This allows it to convect, which aids in plate movement.
What feature of the mantle allows movement of Earth's crust to occur?
The proces is called convection
Where does the Mohorovicic discontinuity occur?
Crust and Mantle.
The mohorovicic discontinuity occur between the crust and the?
mantle
What is the layer of the earth where volcanoes occur?
crust and mantle
What is subtuction?
the movement of rocks and mantle beneath the earth crust
Convection currents within the Earth cause plate tectonics due to the movement of the mantle true or false?
No. Convection currents which could lead to volcanism in the crust occur in the mantle. The crust is too cold and brittle for convection currents to occur.
Convegent boundarie what changes to the crust occur?
The crust is compressed into mountains (if it is continental crust) or subducted back into the mantle if it is oceanic crust.
What is the layer of earth under the crust in which plate movement is generated?
the mantle
A change in the temperature of the core would affect?
Movement of mantle and crust
What is caused by the movement of the plates?
The movement of the hot mantle has broken the crust apart into large plates.
Describe the movement of the crust at a hotspot?
The crust moves in 1 direction at a hotspot due to the convection currents of the mantle
