What zone is know as the hadopelagic zone?

• A. Trenches
• B. Hadopelagic zone
• C. Abyss
• D. Abyssopelagic zone

Answer: (A)

The deepest part of the ocean is the hadopelagic (hadal) zone, which sits in ocean trenches and spans roughly 6,000 to 11,000 meters below the surface. This zone is defined by extreme pressure, cold temperatures, and total darkness, hosting unique life adapted to those conditions. Trenches describe the topography where this zone occurs, not the depth range itself, so the zone is named for its depth: the hadopelagic zone. The other terms refer to shallower depth bands or are not the name of a depth zone, so they don’t capture the deepest ocean environment found specifically in trenches.
