If asked: “what is the tallest mountain on earth?” Most would answer “Mount Everest” without hesitation. They would be wrong. Mount Everest is tall and does hold a record. The peak is the highest point above sea level at 8848 metres. However, NB that is above sea level. Everest is not the tallest mount from base to peak. That title goes to Mauna Kea, which measured from base to peak is 10000 metres. Mauna Kea is mostly underwater and only raises 4205 metres above sea-level. Furthermore, Mount Everest is not even the furthest point from the centre of the earth. That goes to Mount Chimborazo, which is 3967 miles from Earth’s core (Everest is 3965 miles from the Earth’s centre).
