The answer to this question depends on how you define "largest". If you're looking for the mountain with the highest elevation above sea level, then Mount Everest is the largest mountain in the world, reaching approximately 8,848 meters (29,029 feet).
However, if you consider the height from the base to the peak, then Mauna Kea, a dormant volcano in Hawaii, takes the title. Mauna Kea rises 10,203 meters (33,474 feet) from its base on the ocean floor to its summit, making it the tallest mountain on Earth when measured from base to peak.
Mount Chimborazo in Ecuador is another contender for the title of "largest mountain". While its summit is not as high as Mount Everest, it is located farther from the Earth's center due to the Earth's equatorial bulge. This makes Mount Chimborazo the furthest point on Earth's surface from its center.
Therefore, the answer to the question of "Which is the largest mountain in the world?" is not a simple one. It depends on how you define "largest".
