Answer 2

Explanation:

On the basis of Tharp's efforts and other new discoveries about the deep-ocean floor, Hess postulated that molten material from Earth's mantle continuously wells up along the crests of the mid-ocean ridges that wind for nearly 80,000 km (50,000 miles) through all the world's oceans.
