Question
- A. The Earth's crust is divided into large plates that move.
- B. The Earth is a solid sphere with no internal movement.
- C. Volcanoes are formed only at the equator.
- D. Earthquakes occur randomly without any pattern.
Answer
The Earth's crust is divided into large plates that move.
Explanation
Plate tectonics theory states that the Earth's lithosphere is divided into tectonic plates that float on the semi-fluid asthenosphere, leading to geological activity.
Common mistake
Misunderstanding Plate Movement
Students often confuse the movement of tectonic plates with the movement of the Earth's surface as a whole, thinking that the entire surface moves uniformly.
Clarify that tectonic plates are rigid segments of the Earth's lithosphere that move independently over the semi-fluid asthenosphere, and emphasize the different types of plate boundaries and their specific movements.
