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.

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).
Which layers of the earth does convection occur?
Convection occurs mainly in the mantle, which is the layer beneath the Earth's crust. The heat generated by the core causes convection currents in the mantle, leading to the movement of tectonic plates.
Where in the earth do convection currents occur?
Convection currents occur in the Earth's mantle, which is the layer beneath the Earth's crust. These currents are responsible for driving the movement of tectonic plates on the Earth's surface, leading to phenomena like earthquakes and volcanic activity.
Which earth layer is found under the crust?
35 - 60 Kms would be the uppermost mantle, which along with the crust forms the hard, brittle lithosphere. The Mantle is a semi-molten layer.
How is heat transfer in the earths mantle related to the movement of the earths crust?
Heat transfer in the Earth's mantle drives the movement of the Earth's crust through the process of convection. As mantle material heats up, it becomes less dense and rises, causing the overlying crust to move. At the same time, cooler mantle material sinks back down, completing the cycle of heat transfer and driving the continuous motion of tectonic plates.
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.
What feature of the mantle allows movement of the earths crust occur?
The convective currents in the mantle, driven by heat from the Earth's core, allow for the movement of the Earth's crust. This movement results in phenomena like plate tectonics, where tectonic plates interact at their boundaries, leading to earthquakes, volcanoes, and the creation of mountains.
The mohorovicic discontinuity occur between the crust and the?
mantle
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).
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.
Which layers of the earth does convection occur?
Convection occurs mainly in the mantle, which is the layer beneath the Earth's crust. The heat generated by the core causes convection currents in the mantle, leading to the movement of tectonic plates.
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.
Where in the earth do convection currents occur?
Convection currents occur in the Earth's mantle, which is the layer beneath the Earth's crust. These currents are responsible for driving the movement of tectonic plates on the Earth's surface, leading to phenomena like earthquakes and volcanic activity.
What is the layer of earth under the crust in which plate movement is generated?
the mantle
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
How does heat transfer from the mantle relate to the movement of earths crust?
Heat transfer from the mantle creates convection currents that drive the movement of Earth's crustal plates. As hotter mantle material rises, it pushes the crust apart at mid-ocean ridges, while cooler material sinks, pulling the crust down in subduction zones. This movement of the crust is known as plate tectonics.
