Question

The earth’s plate responsible for causing earthquakes is

• A. the crust of the earth
• B. the mantle of the earth
• C. the inner core of the earth
• D. the outer core of the earth

Answer 1

The correct option is A

the crust of the earth

The explanation for correct answer:

Option (A): The crust of the earth

1. Earth comprises four separate layers.
2. The inner core, the outer core, mantle, and crust are the four layers of the earth.
3. The outer layer of the planet (earth's crust) is made up of several pieces, called plates.
4. The movement of the earth's plates causes earthquakes.
5. Oceanic plates are the plates under the oceans; the rest are continental plates.
6. The plates constantly move slowly because of the motion of the mantle that lies underneath the crust.
7. Sometimes friction between the plates causes them to lock together, making it difficult to move.
8. However, the rest of the plates carry on moving and leading to increased pressure on the locked section.
9. Eventually, the locked section fails to resist pressure, and thus the plates move past each other rapidly.
10. This movement of the plates causes the earthquake.
11. The waves of released energy move through the earth's crust and cause the shaking feel at that earthquake site.

Hence the correct option is (A).
