Convection Currents in the mantle powered by the core

Elastic deformation leads to earthquakes because

With enough stress, the rocks slip along the fault releasing energy.

What types of energy power plate tectonics?

geothermal, kinetic, and gravitational

Along faults due to sliding plates

But if continental crust is so much thicker than oceanic crust, why doesn't it sink down below the oceanic crust?

The oceanic crust is denser than the Continental crust

The convection process in the Earth is caused by?*

Hot material from deep in the Earth rises while cooler material sinks.

None
9
Elastic deformation leads to earthquakes because
NONE
With enough stress, the rocks slip along the fault releasing energy.
With pressure, plates stop moving forward & reverse thus releasing energy
