Why Do Earthquakes Occurs ?

Let’s try to first understand what an earthquake is: this may be said to be a violent
and sudden shaking of the ground as a result of movement within the earth’s crust or
even due to volcanic action. The inner core, outer core, mantle and crust are four
types of this earth. The mantle and crust make a thin layer on the surface of our
planet, but this layer is not all in one piece, it is made up of many pieces covering
the earth’s surface. These pieces are always moving past one another and sometimes
even pump into each other. Whenever these pieces of plates move too far from each
other, we experience a situation where the earthquake occurs, because the plates
holding the earth together have lost grip.
