Who is credited with developing the theory of Continental Drift?
Harry Hess
Alfred Wegner

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
What evidence did Wegener use in his theory?
Continents and fossils fitting together/matching-up like puzzle pieces
glacier scars and evidence from temperature
mountain ranges and coal deposits line up across continents
All of the Above

What are the three types of Evidence that supports Alfred Wegener's Theory?
Fossils, Fish, and Land
Sedimentary, Magma, and Climate
Fossils, Land forms, and Climate
Climate, Land forms, and Metamorphic rock
The following are animal fossil evidences of the Continental Drift theory except?
Glossopteris
