The point at which the continent stops and the rock of the ocean floor begins is the called the continental
A. shelf.
B. divide.
C. drift.
D. slope.
is it d ?
The correct answer is A. shelf.
To determine the correct answer, we can first understand the definitions of each option:
A. Shelf: The continental shelf is the extended portion of a continent that is submerged underwater. It is a flat, shallow area that gradually slopes downward from the coastline before dropping off into deeper ocean waters.
B. Divide: In the context of continents and ocean floors, divide refers to a high point or ridge where the waters on either side flow in different directions, such as the continental divide in North America.
C. Drift: Drift generally refers to the movement of objects or substances in a body of water or air due to currents or winds. In this context, it does not directly relate to the point where the continent stops and the ocean floor begins.
D. Slope: A slope refers to a gradual, inclined surface or continuous descent. While the continental slope does exist, it refers to the steep incline that exists between the continental shelf and the deep ocean floor.
Given these definitions, the option A, continental shelf, best fits the description of the point where the continent stops and the rock of the ocean floor begins. Therefore, the correct answer is A. shelf.
