Which theory states that Earth's lithosphere is divided into moving pieces? plate tectonics convection theory continental drift Robinson's theory

The correct answer is: **Plate tectonics** **Explanation:** Plate tectonics is the scientific theory that describes the large-scale movement of Earth's lithosphere, which is divided into several rigid plates. These plates float on the semi-fluid asthenosphere beneath them and move relative to one another, leading to geological activities such as earthquakes, volcanic eruptions, and the formation of mountain ranges. - **Plate Tectonics:** Explains the movement of Earth's lithospheric plates. - **Convection Theory:** Often refers to the movement within the Earth's mantle that drives plate movements but doesn't specifically divide the lithosphere into plates. - **Continental Drift:** An earlier theory proposed by Alfred Wegener suggesting that continents move across the Earth's surface, which later became a fundamental part of the plate tectonics theory. - **Robinson's Theory:** This is not a recognized theory related to Earth's lithosphere or plate movements.
