Layers of the Earth

Which layer makes up most of the interior volume of the Earth?

• Mantle

• Crust

• Inner Core

• Outer Core

Sally is researching the differences that exist in each layer of the Earth. Which of the following best describes Earth's crust?

• Solid, rocky

• Liquid, metallic

• Semisolid, convecting

• Dense, extremely hot

What is the correct order (starting from the surface) of Earth's layers?

• crust, outer core, inner core, mantle
• mantle, outer core, inner core, crust
• crust, mantle, outer core, inner core
• outer core, inner core, crust, mantle

Which layer of the Earth is the only liquid layer?

• Outer Core
• Inner Core
• Mantle
• Lithosphere

Which is true about oceanic crust?

• It is thinner and less dense than continental crust

• It is thinner and more dense than continental crust

• It is thicker and more dense than continental crust

• It is thicker and less dense than continental crust

As you travel from the crust to the core, how would temperature, pressure and density of the material change?

• They would all increase

• They would all decrease.

• Nothing, the layers are made of the same material throughout

• Temperature would decrease, but pressure and density would increase

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.
