Question

Which of the following is not likely to cause an earthquake?

• A. An underground nuclear explosion
• B. Meteor hitting the earth
• C. Volcanic eruption
• D. Lightning

Answer 1

The correct option is D Lightning

An earthquake is a sudden shaking or trembling of the earth which lasts for a very short time. It is not likely to occur in case of lightning, because lightning is an electric spark caused by the accumulation of charges in the clouds. However, earthquakes are much more likely to occur due to underground nuclear explosions, meteor hitting the earth, and volcanic eruptions because of the impact created by these events on the surface of the earth.
