What term describes the gradually sloping submerged extension of a continent, composed of granitic rock overlain by sediments, with features similar to the edge of the nearby continent?

• A. Continental Slope
• B. Continental Margin
• C. Continental Shelf
• D. Fracture Zone

Answer: (C)

The term describes the gently sloping, submerged edge of a continent that is underlain by granitic crust and covered with sediments. This offshore extension matches the land's geology and resembles the continent itself, just underwater. A continental shelf forms the shallow, broad platform before the steeper continental slope drops away, and its rock is the granitic continental crust with sediments accumulating on top from rivers and weathering of the land. The other options don’t fit: the continental slope is the steeper transition zone, not the gradual offshore edge; the continental margin is the broader region that includes shelf, slope, and rise; and a fracture zone is a tectonic feature unrelated to the continental edge.
