According to plate tectonics theory,large convection cells circulate molten rock in different directions within Earth's mantle.

Question

Quizplus · Accepted Answer

Plate tectonics theory proposes that the lithosphere is made up of plates that move and interact with each other due to the circulation of molten rock in the mantle, which is driven by convection currents. The process of mantle convection is responsible for various geological phenomena, including earthquakes, volcanoes, and the formation of mountains and oceanic trenches.
