Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
The ocean floor has several distinct relief features, including shelves, slopes, ridges and deep cut valleys.
Step 1:
Submarine canyons are steep, deep V-shaped valleys carved into the continental shelf and slope. They are often found seaward of large rivers and are formed mainly by turbidity currents carrying sediment down the slope.
Step 2:
Seamounts and guyots are submerged volcanic peaks, atolls and reefs are coral structures, and mid-oceanic ridges are underwater mountain chains. The deep valleys cutting across the shelf and slope specifically match submarine canyons.
Answer: Option (1) — Submarine Canyons.
