Question

Quizplus · Accepted Answer

Plate tectonics is the theory that describes the motion of the Earth's lithosphere, which is composed of several large plates that move and interact with each other, resulting in geological events such as earthquakes, volcanic eruptions, and the formation of mountain ranges. Choice B (Sea floor spreading) and choice C (Pangaea) are both related to plate tectonics but do not fully describe the motion of the Earth's lithosphere. Choice D (Metamorphism) is a process in which rocks are changed due to heat, pressure, and chemical reactions and is not related to plate tectonics.
