Which among the following are Minor Relief features on the Ocean floor?
(A) Guyots
(B) Submarine Canyons
(C) Seamount
(D) Continental slope
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A), (B) and (C) only
The relief of the ocean floor is divided into two groups:
Major relief features — continental shelf, continental slope, deep sea plain, oceanic deeps
Minor relief features — mid-oceanic ridges, seamounts, submarine canyons, guyots, atolls
(A) Guyots Correct. A guyot is a flat-topped seamount, its top worn flat by waves before it sank below the sea.
(B) Submarine Canyons Correct. These are deep, steep-sided valleys cut into the continental shelf and slope, often at the mouths of large rivers.
(C) Seamount Correct. A seamount is a mountain with a pointed top, usually volcanic, that rises from the sea floor but does not reach the surface.
(D) Continental slope Incorrect. The slope that joins the continental shelf to the deep ocean basin is one of the major relief features; it marks the edge of the continent.
