Inside the Earth Review (unit 2)

List the four layers of Earth (from the outer layer to the inner layer).

• Crust, mantle, outer core, inner core

• Mantle, lava, crust, iron

• Inner core, outer core, crust, mantle

• Crust, outer core, inner core, nickel

How do the heat, pressure, and density change as you go deeper inside the Earth?

• The temperature increases but the pressure decreases, and materials get less dense.

• It gets hotter, pressure increases, and materials get denser.

• The temperature stays the same but the pressure decreases.

• Materials get less dense but much hotter.
