How are continental drift and plate tectonics related and how do they influence the movement of Earth's lithosphere?

Continental drift and plate tectonics are related because they both involve the movement of Earth's lithosphere. Continental drift is the theory that continents have moved over time, while plate tectonics is the theory that Earth's lithosphere is divided into plates that move and interact with each other. The movement of these plates is influenced by the forces of convection currents in the mantle, which cause the plates to move and collide, leading to processes like subduction, seafloor spreading, and mountain building. Overall, continental drift and plate tectonics work together to shape the Earth's surface and influence the movement of its lithosphere.
