The mountain with the highest elevation above sea level is Mount Everest, with a height of 29,035 feet. However, the mountain with the greatest elevation between its foot and its summit is the island of Mauna Kea in Hawaii.
The summit of Mauna Kea rises 13,796 feet above sea level, which is far less than Everest, but the foot of Mauna Kea is on the floor of the Pacific Ocean, making the total distance from foot to summit nearly 32,900 feet. The summit of Mount Chimborazo in Ecuador is the most distant point on Earth from the Earth's center. Chimborazo's summit is only 20,730 feet above sea level, but because it is located near the equator where the Earth is at its widest, its summit is slightly farther from the Earth's center than Everest's.
