Question: Which volcano is the world’s tallest mountain from base to peak?
Chimborazo, Ecuador
Mount Kilimanjaro, Tanzania
Mauna Kea, Hawaii
Mount Rainier, Washington
Mount Everest reaches the highest altitude of any mountain on Earth, at 29,029 feet above sea level, but it is not actually the world’s tallest when measured from base to peak. From its base, which is submerged deep in the Pacific Ocean, Mauna Kea measures 33,497 feet in total (although its summit is only 13,803 feet above sea level). The extinct volcano last erupted about 4,600 years ago.
The Answer: The correct answer is Mauna Kea, Hawaii.
