| oceanic crust | this type of crust is thinner, denser and younger than continental crust |
| continental crust | this type of crust is thicker, less dense and older than oceanic crust |
| magnetic field | caused by the rotation of Earth as the outer core circulates around the inner core |
| outer core | layer of earth between mantle and inner core molten metal; liquid iron and nickel; denser than the crust and mantle but not as dense as the inner core |
| inner core | innermost layer of earth; densest layer; solid iron/nickel |
| crust | the outer most layer of the earth; the thinnest/least dense layer; made of rock |
