Detailed explanation-1: -The main horizontal zones are the intertidal, neritic, and open ocean. The benthic zone consists of the bottom of the ocean and the organisms that comprise it. This zone includes the intertidal zone, neritic zone, bathyal zone, abyssal and hadal zones. The area between high and low tide is known as the intertidal zone.

Detailed explanation-2: -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-3: -The intertidal zone is the area of the seafloor between high tide and low tide. It bridges the gap between land and water. Tide pools, estuaries, mangrove swamps and rocky coastal areas are all part of the intertidal zone. The water above the continental shelf is the neritic zone.
