In which ocean is the 'Ninety East Ridge' located?
Appeared in: DSSSB - 28 August 2019 (Shift-1)
Explanation
The Ninety East Ridge is a prominent mid-ocean ridge located on the floor of the Indian Ocean.
It is named for its location as it runs nearly parallel to the 90th meridian east longitude.
This massive underwater mountain range is approximately 5,000 kilometers long and separates the East Indian Ocean from the West Indian Ocean.
Why Other Options Were Wrong
Option A: The Atlantic Ocean is home to the Mid-Atlantic Ridge, a major undersea mountain range that runs down the center of the ocean, not the Ninety East Ridge.
Option C: The Arctic Ocean contains the Gakkel Ridge, which is the slowest-spreading mid-ocean ridge on Earth, not the Ninety East Ridge.
Option D: The Pacific Ocean features the East Pacific Rise, another major mid-ocean ridge, but not the Ninety East Ridge.

Clinical Relevance
Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Geography of major submarine oceanic ridges as background academic context rather than a clinical decision trigger.
General knowledge questions are frequently included in competitive examinations, including those for nursing recruitment, to assess a candidate's overall awareness and intellectual curiosity.
Understanding basic world geography demonstrates a well-rounded education, which is a desirable trait for professional roles.
What if the question asked about the Mariana Trench? The answer would be the Pacific Ocean, as it is the deepest oceanic trench on Earth.
How to Approach the Question
First, identify the key terms in the question: 'Ninety East Ridge' and 'ocean'.
The name 'Ninety East' is a strong clue, suggesting a connection to the 90th meridian east longitude.
Access your knowledge of world geography and major oceanic features. Recall which ocean is associated with the Eastern Hemisphere and the Indian subcontinent.
If you are unsure, try to eliminate other options by recalling the major ridges in other oceans (e.g., Mid-Atlantic Ridge in the Atlantic).
Select the option that aligns with the geographical clue in the name.
