Section A: The challenge of natural hazards

Question

A. Gravity and thermal convection in the mantle.
B. Wind patterns in the atmosphere.
C. Ocean currents.
D. Human activities.

Answer

The correct answer is Gravity and thermal convection in the mantle..

Explanation

The correct option is Gravity and thermal convection in the mantle.. Gravity and thermal convection in the mantle. is correct because it directly matches the approved learning objective to describe plate tectonics theory. This belongs to Tectonic hazards within Section A: The challenge of natural hazards, so the answer must stay focused on the geographical process, evidence, place, or impact named by the curriculum. The other options are weaker because they move away from Tectonic hazards, reverse the geographical relationship, or make a broader claim than the objective supports.

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.
