Nobody has made it to the center of the Earth—but not for lack of trying. In this episode of Crash Course Geology, we’ll journey through the crust and mantle that make up ⅔ of our planet’s insides. We’ll uncover how these layers affect our lives on the surface, and how geologists discover more about them without traveling into Earth’s depths themselves.
