Answer to Question 1

The Challenger Deep is an area of the Mariana Trench (the deepest area in the ocean) in the
Pacific Ocean discovered in 1951 by the British oceanographic research vessel Challenger II.
In 1960, U.S. Navy Lieutenant Don Walsh and Dr. Jacques Piccard became the first to
descend in a submersible vehicle to a depth of 11,022 meters (6.85 miles) into Challenger
Deep. The vehicle they used in the descent was the Trieste, a deep-diving submersible
designed like a blimp.

Answer to Question 2

Oceanic trenches are more prevalent in the Pacific Ocean compared to the Atlantic
Ocean due to the processes that form them. Trenches are formed at convergent zones
where ocean floor is subducted into the mantle. At these intersections, deep trenches
are formed. The Pacific Ocean is a much more active area with a high prevalence of
convergent zones compared to the Atlantic.
