Just learned that the sand on some Florida beaches is actually ground-up quartz from the Appalachian Mountains

I was watching a nature show about the Gulf Coast and they mentioned this fact. The sand on places like Clearwater Beach isn't local. It's quartz that eroded from the Appalachians over millions of years. Rivers carried it down, and ocean currents moved it around the coast. I always thought beach sand was just broken-up shells and local rock. Finding out it traveled that far, from an old mountain range to a beach I've visited, really surprised me. It makes you think about how connected everything is, geologically. Has anyone else come across a fact that made a common rock or landscape seem totally different?
