Because this is why we have continents in the first place. Without the light, thick crust, we’d all be swimming.
It’s also why volcanoes pop up where oceanic crust meets continental crust. The heavy stuff dives under, melts, and boom—Mount St. Helens.
And let’s not forget plate tectonics. The whole system runs on this crusty duo. It’s like a planetary engine powered by rocks.
So next time you step outside, give a little nod to the ground. You’re standing on a 4-billion-year-old pancake of drama.
And if you’re at the beach? You’re walking on a teenager’s forgotten science project. Nice.
