The answer to this question is plates.
It is a fault.
Volcano.
The Earths crust is approximately 650 km deep.
Vent
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
mantle
The earth's crust is not stress
silicate mineral group, which includes minerals such as quartz, feldspar, mica, and olivine. These minerals make up about 90% of the Earth's crust and are the building blocks of most rocks.
An earthquake occurs deep in the earths crust caused by the displacement of two faults in the crust. Directly above the fault on the earths surface is called the epicenter. Which shows the aftermath of the strike slip fault that occured in the earths crust. So the strike slip fault is the effect of the displacement of the crust at that point deep in the earths crust which causes an earthquake to happen whenever there is a displacement of two faults.

continental crust
The earth's crust is generally solid.
