A theory about the earth's structure?
The Earth has a layered structure consisting of the inner core, outer core, mantle, and crust. The inner core is solid iron, the outer core is liquid iron, the mantle is mostly solid but can flow like a very thick liquid over long timescales, and the crust is the Earth's thin outer shell where we live. This structure is known as the "D-layered Earth model."
