The tectonic plates of Earth's crust are always moving, but the movement is far too slow to be perceived without sensitive measuring equipment. For example, the northward movement of India at the rate of two inches per year is considered fast. Usually the only times we perceive the movement of Earth's crust are when part of a tectonic plate gets stuck, and the movement of the rest of the plate causes potential energy to build up in the stuck part until it has enough energy to free itself and catch up with the rest of the plate. That is how most earthquakes happen.

Why the crust move?

the earth's crust is made up of 7 rigid,irregularly shaped plates(slabs). these are called lithospheric plates. these plates move because of the molten magma under the earth's crust which move in a circular motion that's why the earth's crust moves and earthquakes occurs

What explains the movement of the Earth?

The earth's crust moves because the earth has tectonic plates that move because the magma under the earth's surface is constantly boiling. Since the water moves, it causes the earth's crust to move.
