The break is a fault in the rock that can lead to an earthquake, whose tremors can cause much damage to property and death.

faults
The force strong enough to break the Earth's crust is usually associated with tectonic plate movements. These movements occur due to the movement of molten rock in the Earth's mantle, which exerts pressure on the crust. Subduction zones, where one tectonic plate is forced beneath another, and divergent boundaries, where tectonic plates move apart, are common areas where the Earth's crust can break and create earthquakes and volcanic activity.
Magma is molten rock that bubbles up along ocean ridges to form new crust. Another way that magma forms new crust is when it is expelled out of a volcano and becomes lava, which cools and hardens into crust.

A fault.
yes they are. Because all the plate tectonics are part of earth's crust so basically, when they move, they somehow break the crust (which is made of rock)

faults
A break in the Earth's crust along which there has been some movement is a fault. A fault is considered a planar fracture.
The fraction/break itself is a fault caused by tectonic plate movement.
The rock in the lower mantle moves around easily than the crust. This is because rock in the lower mantle is hotter and closer to its melting point. Rocks in the crust are cooler thus harder to move around.
The Earth's tectonic plates do not move on top of the crust, they are the crust. The crust is made out of plates. The plates float on top of the mantle, which is made of molten rock, called magma. The plates move because of currents in the magma.
The crust melt's because the molten rock's are at a really high temperature.
The foliations in a rock are often planes of weakness where there is less cohesion. The rock can therefore break along these foliations.
