The 마리아나 판 is the deepest part of the world's oceans, located in the 태평양. It reaches a depth of about 10,994 meters (36,070 feet) and is known for its extreme conditions, including high pressure and low temperatures. The trench is a result of tectonic plate movements, where the 필리핀 해판 is being subducted beneath the 태평양 판. Exploration of the 마리아나 판 has revealed unique ecosystems and species that thrive in such harsh environments. Notable expeditions, such as those led by James Cameron and various research submersibles, have provided valuable insights into deep-sea biology and geology, highlighting the importance of this mysterious underwater region.
