Trivia: What natural feature is located off the coast of the Mariana Islands?
World’s deepest trench
Oldest coral reef system
Closest glacier to the equator
World’s largest volcano
The correct answer is World’s deepest trench
So why is this answer correct? : The Mariana Trench is a crescent-shaped depression that descends roughly 36,000 feet deep, making it the deepest trench on Earth. To put its depth into perspective, if Mount Everest were placed inside the trench, its peak would still be a mile underwater. At Challenger Deep, the trench’s deepest point, remotely operated underwater vehicles explore the alien-like world devoid of natural light.
