Which answer best describes the continental shelf?

Question

area of land that drops toward deep ocean basins

thick deposits of sediments carried out from land

the surf area along coastlines

75-mile shallow flat area just off coastlines

Answer 1

The best answer that describes the continental shelf is:

75-mile shallow flat area just off coastlines.

The continental shelf is generally a relatively shallow area of the ocean floor that extends from the coastline out to the point where the sea floor drops off into deeper water. While the specific distance can vary by location, it is typically within this range of shallow depths.
