At a specific spot along the coast of North Carolina, the continental shelf extends out 65 m from the shoreline into the ocean. At that point, the
depth of the water is 85 m. From there, the ocean floor slopes down to the oceanic crust which begins 115 m from the shoreline at a depth of
2800 m. Find the slope of the ocean floor connecting the edge of the continental shelf and the beginning of the oceanic crust. That section of
the ocean floor is called the continental slope.
