Question

Explain how an earthquake occurs

Answer 1

the earthquake occurs due to the movement of tactonic plates which present in the earth crust

Answer 2

Answer:

An earthquake is the shaking of the surface of Earth due to the sudden release of energy in the Earth’s crust, as a result, seismic waves (also known as S waves)are created. The seismic activities in an area determine the type and intensity of the earthquake.

Occurrence

Earthquakes are caused when rocks underground break. Earthquakes are caused due to sudden tectonic movements in the earth’s crust. When the tectonic plates slide over one another, there is a cause of orogeny which results in earthquakes and volcanoes. These disturbances cause vibrations that spread in all directions.
