GEOLOGY

Detailed explanation-1: -The depths from 1, 000-4, 000 meters (3, 300-13, 100 feet) comprise the bathypelagic zone. Due to its constant darkness, this zone is also called the midnight zone. The only light at this depth and lower comes from the bioluminescence of the animals themselves.

Detailed explanation-2: -Bthypelagic Zone-The next layer is called the bathypelagic zone. It is sometimes referred to as the midnight zone or the dark zone. This zone extends from 1, 000 meters (3, 281 feet) down to 4, 000 meters (13, 124 feet).

Detailed explanation-3: -The ocean water column is made up of five zones: the sunlight zone (epipelagic), the twilight zone (mesopelagic), the midnight zone (bathypelagic), the abyssal zone (abyssopelagic) and the hadal zone (trenches).

Detailed explanation-4: -The midnight zone is the single largest habitat on the planet, accounting for 70% of all seawater, but because of its remote location, it is poorly understood.

Detailed explanation-5: -Below the mesopelagic zone is the abyssopelagic zone; in most regions of the open ocean, it is the deepest zone. This zone usually extends to the ocean bottom and, combined with the mesopelagic zone, makes up roughly 75 percent of all the ocean’s volume. This zone extends to about 6000 meters deep.
