Everest

S2, E8: It is the tallest and biggest mountain on earth, as far removed from sea level as it's possible to be - and yet its sedimentary layers contain fossils that were once creatures that lived on the ocean seabed. The Himalayas formed when India smashed into Asia - propelled by plate tectonics. Everest is still rising but its height is limited, extreme erosion counteracts and limits the amount of uplift.
