What is the sublittoral zone also known as?

AA. Continental slope

BB. Intertidal zone

CC. Continental shelf

DD. Abyssal plain

Answer:

C. C. Continental shelf

Read Explanation:

  • The continental slope after some distance forming the continental rise which may be geologically active.

  • Continental rise has canyons and trenches which are subject to underwater eruptions and avalanches. The region of the continental slope and rise together comprise the bathyal zone.

  • The bathyal zone which is 200 metres deep descends rapidly to a depth of 3,000 or 4,000 m.

  • From this the bottom drops for further several thousand metres and levels, off around 6,000 m to form the broad flat abyssal plains where temperature is never above 4°C.
