What does the diagram show about earth s interior. The continental crust is the coolest region. Contains the crust and the top most part of the mantle.
The middle portion of the mantle that is made of hot rock that can flow. It is the thin relatively outermost layer that wraps around the earth and ranges in. Earth s crust is what we walk on every day.
At the heart of our planet lies a solid iron ball about as hot as the surface of the sun. It is the outermost and thinnest layer of our planet and is least dense among all other layers. 475 k 200 c at the surface to 1300 k 1000 c thickness.
