EAPS 106 Exam 1, Review Questions and answers, rated A+ How the Earth acquired its internal heat From internal collisions Why the interior of the Earth is layered (crust, mantle, core) and the relative thickness of the layers When the Earth was being created, heavier metals that are more dense (iron and nickel) sank to create the core. Lighter materials such as silicon and oxygen floated to become the crust and mantel. Crust is thin, mantle and core are miles thick (Earth is like a pea...
