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

What 2 layers make up the lithosphere?

• Lower mantle and core

• Core and Crust

• Crust and upper mantle

• Only the mantle

What is the difference between the outer core and inner core?

• There is not a difference. They are both the same.

• Inner core is liquid and the outer core is solid.

• Inner core is solid and the outer core is liquid.
