One of the definite geological destinations in my "Must Do" list was visiting the "Tallest Mountain in the World". Now, that's not Mount Everest, which is the highest point above sea level. When measuring the tallest mountain in the world, you need to measure it from the base of the mountain. So here are some of the "tallest" stats:
Highest point above sea level: Mount Everest (at 29,029 feet [8,848 meters]).
Point furthest from the center of the Earth: Mount Chimborazo (at 20,564 feet [6,268 meters]). The Earth is not a perfectly round sphere. The equator bulges a bit so the Earth is a bit larger around the middle than if you measured it around the poles. For that reason Mount Chimborazo in Ecuador ends up being 6,800 feet further from the center of the Earth than Mount Everest.
Tallest Mountain on Earth: Mauna Kea (at 13,803 feet [4,207 meters]). Now, since the bases of both Mount Everest and Mount Chimborazo are on crustal rocks, it causes the heights of both of those mountains to be approximately their elevation above sea level. However, since Mauna Kea is based on the ocean floor, it ends up being a much, MUCH, taller mountain, with the entire height of the mountain measuring at more than 33,500 feet [10,210 meters].

Biggest Mountain on Earth: Mauna Loa (elevation at 13,448 feet [4,100 meters]). Second to Mauna Kea as the tallest mountain in the world, Mauna Loa is the most massive mountain on Earth. Overall, it takes up 9,700 cubic miles of mountain. This is much more than Mount Everest or any other crustal mountains since those are often mixed together as parts of mountain ranges, where Mauna Loa is essentially one massive mountain, with the other four volcanos merging together to form the Big Island of Hawaii. .
