Which of the following layers has the highest temperature?

• outer core

• asthenosphere

• crust

• lower mantle

Which layer is shown in red?

• inner core

• outer core

It is composed of crust and uppermost part of the mantle.

• hydrosphere

• mantle

• lithosphere

• biosphere

As you travel from the inner core to the crust, how would temperature, pressure and density of the material change?

• The would all increase
• They would all decrease.

• Nothing, the layers are made of the same material throughout
• Temperature would decrease, but pressure and density would increase
