Describe how earthquakes are caused on the surface of the earth.

उत्तर
Earthquakes are caused by the sudden release of energy stored in the Earth’s crust due to stress and strain. When the crust is unable to accommodate the stress, it results in a sudden release of energy in the form of shock waves, causing an earthquake. These shocks can occur due to several factors, such as the movement of tectonic plates and volcanic eruptions, and isostatic imbalances caused by diastrophism, which leads to the formation of faults or folds and creates upheavals and depressions on the Earth’s surface.
