It is difficult to study
marine life in the
extreme depths of the
ocean.
Fossils found on the
ocean floor are much
younger than those on
continents.
The ocean floor has
thick layers of
sediments and debris.

Answer 1

Hess' seafloor spreading hypothesis primarily explains the phenomenon of earthquakes occurring at the rim of the Atlantic Ocean. This hypothesis suggests that new oceanic crust is created at mid-ocean ridges as tectonic plates move apart, which can lead to seismic activity as the plates interact with each other. Therefore, the correct choice is:

Earthquakes occur at the rim of the Atlantic Ocean.
