Layers of the Earth and Continental Drift Theory Quiz Review

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

Is a layer of week of soft mantle that is made of rock that flows slowly.  Tectonic plates move on top of this layer. 

• Inner Core
• Asthensophere
• Lithosphere
• Outer Core

Which of the following is one reason Earth's tectonic plates to move?

• energy from the Sun

• magnetic Pole Reversal

• convection currents in the mantle

• faults in Mountain Ranges

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.

Who is Alfred Wegener?

• Wegener is the scientist who first proposed the idea of continental drift.

• Wegener is the scientist who first proposed the idea of seafloor spreading.

• Wegener is the scientist who first proposed the idea of convection currents.

• Wegener is the scientist who discovered mid-ocean ridges.
