Mariana Trench is located in which ocean?

Correct option is B

Ans. (b)
The Mariana Trench, the deepest part of the world's oceans, is located in the Western Pacific Ocean, near the Mariana Islands. It reaches a maximum known depth of approximately 10,984 meters (36,037 feet) at a point called Challenger Deep. The trench is a result of tectonic plate subduction, where the Pacific Plate dives beneath the smaller Mariana Plate.
Information Booster
1. The Challenger Deep was first measured during the HMS Challenger expedition in the 1870s.
2. The trench lies about 200 kilometers east of the Mariana Islands.
3. The Mariana Trench is protected as a part of the Mariana Trench Marine National Monument.
4. Extremophiles, organisms that thrive in harsh conditions, are found here, making it a significant site for biological research.
5. The first manned descent into the trench was by Jacques Piccard and Don Walsh in the bathyscaphe Trieste in 1960.
6. The pressure at the trench’s deepest point is over 1,000 times the standard atmospheric pressure at sea level.
7. The trench is crucial for studying the geology and biodiversity of extreme environments.
Additional Knowledge
· Southern Atlantic Ocean: It is not home to major trenches but features the Mid-Atlantic Ridge, an underwater mountain range.
· Western Pacific Ocean: The Mariana Trench is located here and is known for its tectonic activity and unique ecosystems.
· Eastern Pacific Ocean: Contains the Peru-Chile Trench but not the Mariana Trench.
· Northern Atlantic Ocean: Known for features like the Puerto Rico Trench, but it is not as deep as the Mariana Trench.
