It is pretty amazing how much we know about the inside of the Earth, given that we can only directly observe a small part of it. When we learn about the layers of the Earth, we learn that the crust is very thin, but that is only on the scale of the rest of the Earth. Relative...
The slice you see cut out of the Earth reveals its core, depicted here in bright yellow. Our Earth, structured in layers similar to an onion, consists of a crust, mantle, outer core, and inner core, each with its own specific characteristics. How has the inside of...
