The mantle of Earth is made partly of magma. When magma rises and sinks, this is called ______________. 

• a conduction current
• a hot spot

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

• They would all increase

• They would all decrease.

• They would stay the same.

• Temperature would decrease, but pressure and density would increase.
