Why and where do earthquakes occur ???

We know the Earth has four layers the external center, mantle, inner core and crust. In our world; mantle has a covering and a highest point, mantle makes up a thin skin on the surface. However, this skin is not all in one piece – it is comprised of a couple pieces like a conundrum covering the surface of the earth. That, as well as these riddle parts keeps gradually moving around, floating past each other and finding separately. We call these bewilder pieces structural plates, and the edges of the plates are known as the plate boundaries.

Plate limits are included a couple shortcomings, and most by far of the earthquakes the world over of these oversights. Since the plates edges are undaunted, they slow down out while the straggling leftovers on the plate keeps moving. Finally, at the point when the plate has moved away satisfactory, the edges loosen on one of the slip-ups and there are is an earthquake.
