A Completely Different World the Deeper You Go
As depth increases, light, temperature, and pressure change dramatically, and each layer hosts unique creatures adapted to that specific environment. The Mariana Trench, the deepest point on Earth, sits within the hadal zone β deep enough to fully submerge Mount Everest.
