Question

Identify the causes of an earthquake.

• A. Volcanic eruption
• B. Underground nuclear tests
• C. Fire accidents
• D. Movement of the earth's plates

Answer 1

Answer: (A), (B), (D)

The correct options are
A Volcanic eruption
B Underground nuclear tests
D Movement of the earth's plates

Tremors on the earth can be caused when a volcano erupts, or an underground nuclear test is performed that results in a huge explosion. All of these can move or shake the earth's tectonic plates thereby resulting in an earthquake. Depending on how severely the plates move or tremble, the intensity of the earthquake varies.
