The tallest mountain in the world is in America.

Climbers who train for years in the hopes of one day making their way up Mount Everest might be surprised to learn the mountain located on the border between Koshi Province, Nepal and the Tibet Autonomous Region is not, in fact, the world’s tallest mountain. While Mount Everest is the highest mountain above sea level, the world’s tallest mountain is Mauna Kea, which is in the Hawaiian islands. According to the American Geography Portal, when measured from its base on the sea floor to its summit, Mauna Kea is more than 32,000 feet tall, topping Mount Everest by a few thousand feet.
