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

Originally the Continental drift theory was not well received by other scientist. Why?

• There was a competing theory at the time that was more believable.

• There was no data showing the continents ever moved.

• The scientists did not know the force responsible for moving the continents.

• The scientist presenting the data was unreliable.
