Which TWO statements best compare the crust to the rest of the layers.

• The crust surrounds all the other layers and is solid.

• The crust is the innermost layer and is liquid.

• The crust is the thinnest layer and is solid.

Match the layers of earth to the correct description.

• Mantle

• This layer of earth is the thickest layers and is composed of iron, oxygen, silicon, and other minerals.

• Crust

• This layer of earth is the hottest layer and is solid because of the pressure that is put on it from surrounding layers.

• Outer Core

• This layer of earth is a liquid and is composed mainly of iron and nickel.

• Inner Core

• This layer of earth is the outer layer and is the thinnest layer. It is composed of various types of rocks and minerals.

Which of the following layers of Earth has the greatest density?

• crust

• mantle
