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 geologic feature was evidence to support the theory that the continents used to be joined (Select ALL that apply)?
