Earth is divided into a thin outer(prenominal) crust, a solid rocky mantle, and a dense hollow out.
ground on physical properties, the layers of Earth are: (i) the lithosphere (the cool, pixilated outermost layer that averages about 60 miles thick), (ii) the asthenosphere (a relatively clean layer located in the mantle beneath the lithosphere), (iii) the more than rigid lower mantle (where rocks are very savory and capable of very gradual flow), (iv) the liquid outer core (where Earths magnetic field is generated), and (v) the solid inner core. Two tether divisions of Earths surface are the continents and ocean basins. The elevation differences between continents and ocean basins are the result of differences in their respective densities and thicknesses.
Fossils are signs of (once) accompaniment things, found in many sedimentary rocks, and tell us the story of how the Earth was formed and of the history of life on Earth. Fossils take a couple of different forms but they all involve a record of life form maintain in rock.
