You can see the ongoing collision of the Indian subcontinent into the Asian continent creating the Himalayas, fun fact: they're still getting bigger; Everest gets a 1/4th of an inch (6.35 mm) taller every year even with solar and precipitated erosion.
So every person who summits Mt. Everest is technically setting a new record.
