Is K2 growing faster than Everest?

    Both are growing very slowly each year.  K2 is part of the same area of uplift as Mount Everest.  The Himalayas as a whole are the youngest mountain ranges on the planet and consist mostly of uplifted sedimentary and metamorphic rock.  Their formation is a result of continental collision along the converent boundary between the Indo-Australian Plate and the Eurasian Plate – this is referred to as a fold mountain.  The Indo-Autsralian plate is still moving at 67mm per year so both K2 and Everest continue to grow.

    While the Himalayas are presently actively uplifting, it is incorrect to say they are the youngest mountain range. They are no younger than other presently uplifting ranges, including the Andes, Alps, Zagros, Alaska Range, and others, as well as active volcanic ranges such as the Caribbean islands, Japan, the Kurils and Kamchatka, and most of Indonesia. Most of those volcanic mountain ranges began later than the inception of the Himalayas about 40-50 million years ago.

    While Everest and K2 and much of the rest of the Himalayas are indeed uplifting, they are also eroding continuously. Whether a particular area has net increase in height or decrease depends on erosion rates as well as uplift rates. Generally, now, the Himalayas are mostly still in net uplift.
