• crust

• mantle

Which of Earth's layers is shown by the letter Y in the image?

This model is made of wood. The artists wanted to show the structure and relationship of the Earth's layers. How is the model limited from showing this?

• The crust of the model cannot move over the mantle.

• The crust of the model has different features from the mantle.

• The layers of the model do not have the same thickness.

• The inner core of the model does not touch the Earth's surface.
