🗻🌊The deep seabed is defined as the region that is more than 200 meters deep, extending to the abyssal plains that range from 3,000 to 6,000 meters. Beyond these plains are ocean trenches, such as the famous Mariana Trench, which reaches an impressive depth of up to 11,000 meters. These abyssal and hadal areas host a diversity of life adapted to extreme conditions of pressure and darkness, and are crucial for understanding the geological and biological processes that occur in the deep ocean.
