Which of the following best describes a change one would observe in moving from Earth’s crust downward to the outer core?

• Pressure would change from very high to none.

• Density would change from least to most dense.

• Plasticity would change from flexible to rigid.

• Heat would change from relatively hot to cool.

The lithosphere consists of the –

• upper mantle and the crust

• lower mantle and the outer core

• inner and outer core.

• crust and the entire mantle.
