Question

Wegener's theory of continental drift was largely dismissed by the mid-1900s. What new evidence was able to revive this theory, and why?

Answer 1

Answer:

C. The coastlines of South America and Africa were similar in shape, suggesting that they shared a common tectonic plate.

Explanation:

• As suggested by the Alfred Wegener, the plates of the South America and the African plants had a similar geologic history and thus shared a common tectonic boundary and hence validate the proof of the superclass and the drifting of the plates at various time zones.  

• Thus after the 1960s the plate tectonic theory came into the limelight and was heavily recognized to be fit the works of the drifting of the continental landmasses.
