Question

One underwater mountain in the Pacific, _____, is only 500 feet shorter than Mount Everest. Which of the following options fills in the blank appropriately?

A) Mariana Trench
B) Great Barrier Reef
C) Mid-Atlantic Ridge
D) Hawaiian Islands

Answer 1

Maunakea is an underwater mountain in the Pacific that is nearly as tall as Mount Everest, forming part of the Hawaiian Islands and created by volcanic eruptions.

Step-by-step explanation:

The underwater mountain in the Pacific which is only 500 feet shorter than Mount Everest is part of the Hawaiian Islands. Specifically, this refers to a mountain called Maunakea, which is a now-dormant volcano.

Maunakea rises 9 kilometers above the ocean floor and forms part of the Hawaiian island chain that was created through volcanic eruptions over time at a hot spot.

This hot spot has produced a chain that is 3500 kilometers long, encompassing many volcanic islands, with Maunakea being one of the most prominent due to its massive size and elevation.
