The layers of Earth are the crust, mantle, and care, with the core being divided into inner and outer layers. Which of the following does NOT describe the layers of the solid Earth?

• The core makes up the majority of Earth's volume.

• The mantle is composed of rocks known as silicates.

• The core is made up of dense elements, such as iron and nickel

• The crust is extremely thin when compared to the core or mantle.

Which layer of Earth is composed of liquid iron and nickel?

• crust

• inner core, outer core, lower mantle, upper mantle, crust

• lower mantle, upper mantle, crust, inner core, outer core

• lower mantle, inner core, upper mantle, outer core, crust
