Quizplus · Accepted Answer

Plate tectonics is the theory that explains the movement of the Earth's lithosphere, which is divided into several plates that move relatively to each other. The lithospheric plates move due to the convection currents in the underlying mantle, which helps in the movement and spreading of the ocean floor. The theory of plate tectonics also helps to explain many geological phenomena, including earthquakes, volcanic eruptions, and the formation of mountain ranges.
