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

Where does Earth’s magnetic field get its energy from?

• The motion of the Earth's plates colliding with each other.

• The motion of the Earth's liquid core, which generates electric currents.

• The motion of the Earth's mantle which has convection currents.

• The motion of the Earth's rotation around the sun.

• Mid Ocean Ridge

• Subduction Zone

• Rift Valley

• Folded Mountains
