Extremely Deep Land

The Mariana Trench, located in the northwest Pacific Ocean, is the deepest known trench on Earth. Its deepest point is the Challenger Abyss, reaching a depth of approximately 10984 meters. Due to its extreme depth and high-pressure, low-temperature environment, this region has become an important place for scientists to study the tectonic plates of the Earth and deep-sea organisms. Despite the harsh environment, the Mariana Trench still has a unique ecosystem, including some specialized deep-sea organisms that have adapted to the dark, high-pressure, and cold conditions here.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The Mariana Trench is located in the western Pacific Ocean, east of the Mariana Islands and east of the Philippines. It is the deepest part of the world's oceans, with its maximum depth reaching 11034 meters at the Fijaz Deep, which is the deepest known point on Earth. The total length is 2550 kilometers, with the deepest point reaching 6-11 kilometers, making it the deepest known ocean. This area has high water pressure, complete darkness, low temperature, low oxygen content, and scarce food resources, making it one of the most environmentally hostile regions on Earth. There is also life present here. The "little flying elephant octopus" mostly lives at depths of about 3000 to 4000 meters on the seabed, making it the deepest habitat among all octopus species. Its population is very rare, and its characteristic is that it can adapt to extremely cold environments and high-pressure depths of the seabed. The density of continental crust is lighter, while oceanic plates are heavier. When oceanic plates encounter continental plates, heavier oceanic plates will subduct to the continental plates.
