Earthquakes occur when stress resulting from too many changes. This condition occurs most often in the realm of plate tectonics. Divided into lithosphere crust layer.
Earthquakes occur when stress as a result of a change there too. This condition occurs more frequently in the boundaries of tectonic plates. The crust is stratified lithosphere.
The earthquake will occur when the stress resulting from the change is too much. This condition occurs frequently in the scope of the plates. The class divide the earth into the earth.
