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

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

Scientists determine what Earth’s interior looks like by using:

• Volcanoes
• Seismic Waves
• Continental Drift
• Convection Currents

Which crust is thicker

• oceanic

• continental

• they are have the same density so it doesn't matter

• science isn't able to tell yet
