- Statement 1 and 2 are correct about the interior of the Earth. The third one is not true as Earthquake waves are basically of two types — body waves and surface waves.
- Earthquake: Earthquakes are caused by the seismic waves that are generated due to a sudden movement in the earth's crust.
- Earthquakes may occur naturally or as a result of human activities.
- Tectonic earthquakes are generated due to the sliding of rocks along a fault plane.
- Volcanic earthquakes are caused due to violent volcanic eruptions.
- Collapse earthquakes: These type of earthquakes occurs in the areas of intense mining activities.
- Explosive earthquakes: These types of earthquakes arise due to the explosion of chemical or nuclear devices.
