Which of these best describes the lithosphere?

• The lithosphere is made of rock that is weak and easily changed.

• The lithosphere is made of rock that is highly compressed and very hot.

• The lithosphere is made of rock that is molten and does not have a solid shape.

• The lithosphere is made of rock that is cooler and stronger than the other layers.

What characteristic of the outer core makes it unique among the layers of Earth?

• The outer core is liquid due to intense heat.

• The outer core is the coolest layer of the Earth.

• The outer core is made of solid iron, giving it a lot of rigidity.

• The outer core is made of solid rocky material, like what we walk on.

Which statement below best describes how temperature changes in the Earth’s interior as you travel deeper into the Earth?

• The temperature constantly decreases

• The temperature constantly increases

• The temperature constantly decreases then increases

• The temperature constantly increases then decreases

Since the crust floats on top of a liquid and flowing upper mantle, what inference can be made about the density of the two layers?

• The crust is less dense than the upper mantle.

• Both the crust and upper mantle have the same density.

• No inference can be made about the densities of the two layers.

• The crust is denser than the upper mantle.
