Think of continental crust as thick pizza dough. It’s chewy, rises high, and takes forever to bake.
Oceanic crust is like a thin cracker. It’s brittle, sinks fast, and gets eaten up quickly.
Continental crust floats; oceanic crust sinks. That’s why continents stay above water and ocean floors stay, well, wet.
Continental crust is rich in silica and aluminum—scientists call it “sial.” Oceanic crust is full of silica and magnesium—“sima.” Try saying that five times fast.
Oh, and one more thing: Earthquakes love oceanic crust. It’s brittle and snaps easily. Continental crust? It can bend and stretch a bit. Flexible, like a yoga instructor.
