Answer 1

Hess' seafloor spreading hypothesis primarily explains the concept that new oceanic crust is formed at mid-ocean ridges and spreads outward, leading to the ocean floor being younger near the ridges and older farther away. This means that the response that aligns with Hess' seafloor spreading hypothesis is:

Fossils found on the ocean floor are much younger than those on continents.

This is because the process of seafloor spreading creates new crust at mid-ocean ridges, meaning that the ocean floor is generally younger than the continental crust.
