Earthquake : A form of energy of wave motion conveyed through the surface layers of the earth.
An earthquake is a powerful and abrupt movement of the ground surface. It is a display of the power of tectonic forces caused by thermal conditions inside the earth. It can range from a small tremor to a wild motion capable of shaking buildings apart and causing open cracks on the ground.
An earthquake is a form of energy of wave motion conveyed through the surface layers of the earth in the form of widening circles. Sometimes, when earthquakes originate from the middle of the ocean, it causes extremely large and destructive waves called Tsunami. This again results in the loss of many lives.
