Which piece of evidence did Alfred Wegener use to develop the theory of continental drift?

A.

basalts on the ocean floor

B.

undersea mountain ranges

C.

similar fossils on different continents

D.

paleomagnetism on the seafloor

It is c. The underwater mountain chain wasn't discovered until after we he died. The right answer is c because he noticed since all the fossils

line up they must have once been one continent and the continental drift is the theory that the plates spread apart

Alfred Wegener did not have the tools necessary to figure out the other options, so the answer is C.
