Distance

If you measure the distance to the peak of Mount Everest from sea level, then it is the highest mountain.   But if you were to measure from the center of the earth to the peak, then Mount Chimborazo in Ecuador would be considered the highest mountain on Earth.   By this measurement, Mt.

Chimborazo is one degree south of the equator and the Earth’s diameter at the equator is greater than at the latitude of Everest
