Certainly, here are some multiple-choice questions (MCQs) on tectonic plates and earthquakes:
1. What are tectonic plates?
(A) Large pieces of metal beneath the Earth's surface.
(B) Rigid segments of the Earth's lithosphere that move and interact.
(C) The layers of sedimentary rock found at the bottom of oceans.
(D) The uppermost part of Earth's mantle.
Correct Answer: (B)
2. Which of the following is primarily responsible for the movement of tectonic plates?
(A) Gravitational forces from the Moon.
(B) Convection currents in the Earth's mantle.
(C) Solar radiation.
(D) Earth's magnetic field.
Correct Answer: (B)
3. Where do most earthquakes occur?
(A) In the middle of continents.
(B) Along the edges of tectonic plates.
(C) In underground caves.
(D) On the ocean's surface.
