In the extreme long-term geological future, Nanga Parbat is the most likely candidate to overtake Mount Everest as the world's tallest peak. Located in the Himalayas of Pakistan, Nanga Parbat is currently the 9th highest mountain on Earth, but it is the fastest-growing mountain in the world, rising at a rate of approximately 7mm per year due to intense tectonic activity. In comparison, Mount Everest grows at a slower rate of about 4mm per year. If these rates remain constant and erosion patterns don't drastically shift, scientists estimate that Nanga Parbat could surpass Everest in approximately 241,000 years. It is worth noting that "tallest" is a relative term; Mount Chimborazo in Ecuador is already "taller" than Everest if measured from the center of the Earth (due to the equatorial bulge), and Mauna Kea is taller if measured from its base on the ocean floor. However, in terms of altitude above sea level, Nanga Parbat is the "rising star" of the tectonic world, gradually making its way toward the title of the world's highest summit.
