Question

The continental slope comprises of ____________ of the ocean area.

• A. 5%
• B. 10%
• C. 15%
• D. 20%

Answer 1

Answer: (C)

15%

The continental shelf is separated from the continental slope by the shelfedge or shelf-break at approximately 200 m depth. The gradient of the slope ($4^{\circ }$ on an average) is much higher than that of the continental rise $\left(1^{\circ }\right)$. The continental shelf and slope together cover 15% of the total ocean floor, and the continental rise covers about 5%.
