标题：最深的海底深度
文章：
deepest part of the ocean, known as the Mariana Trench, holds the record for the deepest known point on Earth. Located in the western Pacific Ocean, the Mariana Trench reaches a maximum depth of about 36,037 feet (10,994 meters) at a spot called Challenger Deep. This extraordinary depth was first reached and confirmed by the U.S. Navy's bathymetric ship, the USS Challenger, during the HMS Challenger Expedition in 18721876. However, it was not until 1960 that the trench was visited by humans when Jacques Piccard and Don Walsh reached the bottom in the bathyscaphe Trieste.
The Mariana Trench is part of the Pacific Ring of Fire, an area with a high concentration of earthquakes and volcanic activity due to tectonic plate subduction. The trench is formed by the subduction of the Pacific Plate beneath the Philippine Sea Plate.
Here are some key facts about the Mariana Trench:
1. Location: The Mariana Trench is located in the Pacific Ocean, west of the Mariana Islands.
2. Formation: It was formed by the subduction of the Pacific Plate beneath the Philippine Sea Plate.
3. Maximum Depth: The deepest point, Challenger Deep, is about 36,037 feet (10,994 meters) below sea level.
4. Atmospheric Pressure: At the bottom of the trench, the pressure is about 1,086 atmospheres, which is over 14 times the atmospheric pressure at sea level.
5. Temperature: The water temperature near the bottom of the trench is around 1.9掳C (35掳F), which is very cold.
6. Life: Despite the harsh conditions, extremophile organisms, including bacteria and archaea, have been discovered living near the bottom of the trench.
7. Exploration: The first successful dive to the bottom of the Mariana Trench was by Jacques Piccard and Don Walsh in 1960.
8. Recent Exploration: The deepest dive in modern times was in 2012 by film director James Cameron, who traveled to the bottom in a submersible called the Deepsea Challenger.
