Answer:
An earthquake is defined as a tremor below the surface of the earth which causes shaking of the crust. These devastating tremors are caused by the stresses that break the earth's crust.
Earthquakes are caused by the strain in the earth's crust which in turn is a result of a number of factors. When the earth 's crust is unable to accommodate itself to the strain, it results in sudden release of tremendous energy in the form of a sudden violent shock.
