The Composition and Structure of Earth Physical Geography

Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earths mass. Finally, the core is mostly iron metal. The core makes up about 31% of the Earth.The Composition and Structure of Earth Physical GeographyCore, mantle, and crust are divisions based on composition.
