Earthquakes are caused by – (1) Denudation (2) Tectonism (3) Earth revolution (4) Earth rotation
by

1 Answer

Answer :

(2) Tectonism Explanation: Earthquakes result from the sudden release of energy in the Earth's crust that creates seismic waves. Most occur along plate boundaries. Tectonic earth-quakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane.
