• Layers of the Earth
• Composition of the Earth's core

Which of the following is true about the Earths Mantle?

• It is made up of completely solid rock
• It is the largest layer of Earth
• It is the most dense layer of Earth
• It is made up of mostly liquid metals

Which of the following is true about the Earth's Outer core?

• It experiences the most pressure
• It is made up of solid metal
• It is the most dense layer
