Question

Which of the following is a term used to describe the deep and flat portions of the ocean on either side of a mid-ocean ridge? A. abyssal plain B. guyot C. seamount D. trench

Answer 1

Seamount and guyot are types of mountain - so we can reject those options, since we're looking for a flat surface, not a mountain.

A trench is a narrow ditch, or  depression so also it's not a plain

The correct answer is abyssal plain - it's a plain typically next to a continental rise (leading to the continent) and a mid-ocean ridge.
