The correct order of the Earth's layers starting from the OUTSIDE going IN is

• crust, inner core, mantle, outer core

• mantle, outer core, inner core, crust

• crust, mantle, outer core, inner core

• inner core, outer core, mantle, crust

Which layer is made of liquid metal (Fe and Ni)?

• crust

• mantle

• outer core

• inner core

Which layer is the hottest?

• crust

• mantle

• outer core

• inner core

Which layer is the thinnest?

• crust

• mantle

• outer core

• inner core

how did Pangaea break apart

• dynamite

• cave men

• Minecraft

• continental drift theory

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

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
