| continental crust | made mostly of granite/layer where humans live |
| crust | thinnest of Earth's layers |
| crust | coolest of Earth's layers |
| oceanic crust | made mostly of basalt |
| outer core | extremely hot layer of Earth made of liquid iron and nickel |
| inner core | hottest, most dense layer of Earth |
| inner core | composed of solid iron and nickel located at the center of Earth |
| composition | what something is made of |
| lithospehere | the part of the mantle that contains broken pieces called plates |
| fossil | preserved remains or traces of organisms |
| continental drift | theory that states all of Earth's continental crust was together in one giant landmass but is drifting apart |
| Pangea | the Super continent that contained all of Earth's continental crust |
| Alfred Wegener | scientist who proposed the theory of continental drift |
| asthenosphere | the layer of Earth that is a solid but moves like a liquid, it is responsible for the movement of the lithosphere |
| trace fossils | fossils that are signs that an organism was alive (footprints, coprolite, burrows)) |
| body fossils | fossils that are made from parts of an organism's body (shells, teeth, bones) |
| index fossils | fossils of organisms that lived for a relatively short period of geologic time and were widely distributed; used to determine how old rock layers are |
| carbon films | an organism outline of a fossil; this type of fossil can be found in any rock when organic material is compressed, leaving only carbon residue or film |
