Layers of the Earth

Which statement BEST describes one difference between Earth's mantle and crust?

• The mantle is less dense than the crust.

• The mantle is hot compared to the crust.

• The mantle is cool compared to the crust.

The tectonic plates are made of a combination of the crust and the uppermost part of the mantle. What is this combination called?

• asthenosphere

• continental crust

• atmosphere

• lithosphere
