Define earthquake in such a way that it looks as the short note size.

Answer 1

Earthquakes are shaking of the earth's surface. This is caused by a sudden release of energy in the earth's lithosphere which causes seismic waves. Most earthquakes occur along boundaries of tectonic plates and are caused when these plates get suddenly displaced. Other causes of earthquakes include volcanic eruptions and landslides. Severe earthquakes can destroy cities and cause immense amount of death and destruction.
