What is an earthquake and what causes it? [3 MARKS]

Answer 1

Each point: 1 Mark

1. An earthquake is a sudden shaking or trembling of the earth lasting for a very short time.
2. It is caused by a disturbance deep inside the earth’s crust. Earthquakes are usually caused when rock underground suddenly breaks along a fault.
3. This sudden release of energy causes the seismic waves that make the ground shake.
