Continental shelves and continental slopes differ in several ways:

1. Continental shelves are large flat areas on the ocean floor where layers of sediment have covered the original seafloor topography. This means that they are relatively smooth and flat compared to other parts of the ocean floor.

2. Continental shelves are the relatively shallow submerged borders of the continents. They extend from the coastline of a continent to a point where there is a noticeable increase in slope or steepness, known as the shelf break.

3. Continental slopes are where the continental land masses slope downward to the floors of the ocean basins. They are steeper than the continental shelves and mark the true edge of continents.

4. Continental slopes are not isolated submarine volcanic structures. These structures, known as seamounts, are found in various locations across the ocean floor, but they are not part of the continental slope.

In terms of which are the true edges of continents, it would be the continental slopes. While continental shelves are part of the continents, they are submerged and do not mark the edge of the landmass. The continental slope, on the other hand, marks the point where the continent ends and the deep ocean floor begins.
