Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A-III, B-II, C-I, D-IV
Earthquakes are named by what causes the shaking of the ground.
(A) Volcanic Earthquake — this matches (III) confined to areas of active volcanoes. They are caused by the movement of magma and volcanic eruptions, so they occur only near active volcanoes.
(B) Collapse Earthquake — this matches (II) in areas of intense mining activity. There, the roofs of underground mines sometimes collapse and cause minor tremors.
(C) Tectonic Earthquake — this matches (I) due to sliding of rocks along a fault line. These are the most common earthquakes: stress builds up in the rocks until they slip suddenly along a fault.
(D) Explosion Earthquake — this matches (IV) due to chemical or nuclear explosion. The tremors are produced by the explosion of chemical or nuclear devices, not by natural forces.
