B. ALL the crust and ALL the mantle
C. ALL the crust and the uppermost part of the mantle
D. ALL the mantle and the uppermost part of the crust
3. What happens to the temperature and density of each layer as you descend (go down) from the
surface to the center?
A. They both decrease.
B. They both increase.
C. The temperature increases, but the density decreases.
D. The temperature decreases, but the density increases.
4. Which choice has the 5 sub layers in order from coolest to hottest?
A. Inner core, Outer core, Mesosphere, Asthenosphere, Lithosphere
B. Lithosphere, Mesosphere, Asthenosphere, Inner core, Outer core
C. Asthenosphere, Outer core, Mesosphere, Inner core, Lithosphere

5. Match the layer of the earth to the description of each layer.
_____ Lithosphere
a. A syrupy layer that flows and is the 2nd sub layer from the
_____ Asthenosphere
surface.
_____ Mesosphere
b. A truly liquid layer made mostly of nickel
_____ Outer Core
c. A solid layer made of ALL the crust and the uppermost part of
_____ Inner Core
the mantle. It is the least dense and coolest of all 5 layers.
d. It is a solid ball of iron at the center of the earth.
e. The layer just above the outer core whose prefix means “middle.”
