Logan knows that the Earth's lithosphere is divided into pieces known as tectonic plates but he wonders what portion of Earth is considered the lithosphere. Which of the following is true regarding the composition of the lithosphere?

• The lithosphere is mostly liquid, with some medium-density materials, such as silicon.

• The lithosphere is more plastic and flows slowly compared to the solid crust of Earth.

• The lithosphere includes the core and the lower portion of the mantle.

• The lithosphere includes the crust and the uppermost portion of the mantle, which is sold and rigid.

Which of Earth's layers is best described as liquid metal?

• Crust

• Mantle

• Outer core

• Inner core

The layers of Earth are the crust, mantle, and core, 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.

Earth contains distinct layers, including the inner core, outer core, mantle, crust, asthenosphere, and lithosphere. A diagram of Earth's layers is provided. Which letter in the diagram identifies the solid layer of Earth which is made up of mostly magma?

• Layer A

• Layer B

• Layer C

• Layer D

The very top layer of Earth is the crust, which is relatively quite thin when compared to the other layers of Earth. Which of these best describes the composition of Earth's crust?

• Liquid

• Metallic

• Gaseous

• Rocky

Rachel 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, convective

• Dense, extremely hot

We can distinguish the layers of Earth based on their chemical composition and the state of matter or each, that is, whether it is solid or liquid. A diagram of Earth's layers is provided. Which letter in the diagram identifies the layer of Earth made up of solid nickel and iron?

• Layer A

• Layer B

• Layer C

• Layer D
