Earth's crust is divided into various plates which float on hot magma layer called asthenosphere. When these plates move, they interact with each other which releases energy, that is felt on the surface of earth as tremors or shaking movement, which is termed as earthquake.
Cyclones, thunderstorms and lightenings are the atmospheric phenomena and are not related with earth's surface, hence these 3 options are incorrect.
The point on the earth's surface directly above the point of origin of earthquake is called ___________.
An earthquake is the shaking of the surface of the Earth resulting
from a sudden release of energy in the Earth's lithosphere that
creates seismic waves.
An earthquake's
point of initial rupture is called its focus or hypocenter. The
epicenter is the point at ground level directly above the hypocenter
