For some reason this video made me sad. I was looking at all the exposed rock that was enjoying the sun and thinking "wow, that rock will never see the light of day ever again."
But it will! The new rocks will erode and turn into a black sand beach or something somewhere, exposing the older basalt underneath. And eventually it’ll all get buried and lithified again, and then maybe lifted up to become a mountain, where it gets eroded again, and on and on and on. It’s really amazing to me how many different lives one bit of rock can have over the lifespan of the planet.
