Final answer:
The theory of plate tectonics continues to change due to ongoing scientific research and new discoveries.
Step-by-step explanation:
The theory of plate tectonics continues to change due to ongoing scientific research and new discoveries. As scientists gather more data and refine their understanding of the Earth's crust, they may revise or update existing theories to better explain observations. For example, initial theories of plate tectonics did not fully account for the phenomenon of hotspots, but as more evidence emerged, scientists adapted the theory to incorporate these volcanic activities.
