The correct response is:
They showed what the oceans’ floors looked like helped explain how continents move over time.
Marie Tharp and Bruce Heezen's mapping of the ocean floor provided critical evidence for the theory of plate tectonics, demonstrating the existence of mid-ocean ridges, rift valleys, and the movement of tectonic plates, which contributed to our understanding of how continents drift and change over geological time.
