Quizplus · Accepted Answer

As the Mid-Ocean Ridge system spreads, it creates a broader ridge that displaces seawater, causing sea level to rise. This is known as the "oceanic spreading hypothesis" and has been supported by geological evidence from past sea level changes. The other choices are not supported by scientific evidence.
