Which zone is associated with trenches?

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

Answer: (A)

Trenches lie in the deepest parts of the ocean, where pressure is immense and light is scarce. The zone that matches these extreme depths is the hadalpelagic (hadopelagic) zone, which spans roughly from 6,000 to 11,000 meters below the surface and includes the deepest trench environments like the Mariana Trench. So, trenches are best associated with the hadal zone because that is the depth range where trench bottoms occur. The other options refer to either shallower deep-water bands or to a geological feature rather than a depth zone, so they don’t specifically describe the environment found in ocean trenches.
