A student constructs a clay model of Earth to show its layers. What property is the model able to share with the real Earth? The model will have layers that are the same -

• temperatures as the real Earth.

• positions as the real Earth.

• state of matter as the real Earth.

• thickness as the real Earth.

The layer of Earth that is found directly below the lithosphere is called the -

• crust

• asthenosphere

• inner core

• outer core
