chosen.content: The question of which is the tallest mountain in the world is subjective and debatable. Technically, the peak of Mount Everest is considered to be the highest altitude above mean sea level at 29,029 feet, awarding it the name of the tallest mountain. However, the honor of the tallest mountain on earth from base to peak belongs to Mount Mauna Kea, a volcano on the island of Hawaii, which originates deep beneath the Pacific Ocean, rising to more than 33, 500 from base to peak. Also, it's important to note that the highest point above the earth's center is Mount Chimborazo in Ecuador with a summit of 20,564 above sea level.
