________ is a sudden shaking of the Earth’s crust.
The correct option is c)Earthquake.
- An earthquake (also called a tremor, tremor, or tremor) is a shaking of the earth's surface caused by the sudden release of energy in the earth's lithosphere that produces seismic waves.
- The strength of an earthquake can range from weak enough to be felt to strong enough to throw objects and people into the air and destroy entire cities.
- On the earth's surface, earthquakes appear as ground vibrations, displacements, and disturbances. If the epicenter of a large earthquake is offshore, the seafloor may shift and generate a tsunami. Earthquakes can also cause landslides.
