Mauna Kea is over 10,000 meters tall compared to 8,848 meters for Mount Everest – making it the “world’s tallest mountain”. As Mauna Kea has portions beneath the oceans and as a matter of reason Mt. Everest Is regarded as the tallest mountain as altitude is the counting part.But when its everything about height then It is this massive Hawaain Mountain that stands a liitle more high than the Everest!!!
Mauna Kea has an altitude of 4,205 meters (13,796 feet) – much lower than Mount Everest. However, Mauna Kea is an island and if the distance from the bottom of the nearby Pacific Ocean floor to the peak of the island is measured, then Mauna Kea is “taller” than Mount Everest.
