| A | B |
|---|
| inner core's density | densest layer of earth |
| outer core | believed to be the only liquid layer of earth |
| molten rock (magma) | mantle mainly consists of |
| outer core | believed to cause earth's magnetic field |
| inner core | solid iron due to extreme pressure |
| mantle | convection currents occur in this layer |
| continental crust | thickest layer of the crust |
| oceanic crust | thinnest layer of the crust |
| lithosphere | "floats" on top of the asthenosphere; includes all of the crust and the upper part of the mantle |
| asthenosphere | semi-solid layer in mantle where convection currents occur |
| granite and basalt | two types of rocks the crust is primarily made of |
| solid iron and nickel | what the inner core is made of |
| liquid iron and nickel | what the outer core is made of |
| temperature, density, and pressure | 3 factors that increase the deeper you get into the earth |
| water | at least 70% of Earth's crust is covered in this |
