Your teacher has asked you to make a model of the interior of the Earth. In your model, how do the thicknesses of the lithosphere and crust compare?

• The lithosphere is thinner than the crust.

• The lithosphere is exactly the same thickness as the crust.

• The lithosphere is thicker than the crust.

• The lithosphere is thicker than the oceanic crust, but thinner than the continental crust.

Why is the Inner Core solid?

• Extreme Heat

• High Pressure

• All the layers are solid

• It's made of rock

The crust and the uppermost mantle make up the solid layer of hard rock called the

• inner core

• asthenosphere

• lithosphere

• outer core
