What is the process by which the earth formed through gravity bringing together the smaller particles of matter to from a planet? Accretion
What is the outer layer of the earth that is made out of rock; makes the continent and oceans bottom? The crust
What is the outer layer of the core, made of molten metals; iron and nickel? (It gives the earth its magnetic fields.) The outer core
