Continental drift and plate tectonics are the theories that describe the movement of landmasses on Earth's surface. Continental drift suggests that the continents have moved over time, while plate tectonics explains that the Earth's lithosphere is divided into several large plates that move and interact with each other. Subduction and divergence are processes that occur due to plate tectonics. Subduction is when one tectonic plate moves beneath another, and divergence is when two plates move away from each other, creating new crust.
