It would serve as the basis for the theory of plate tectonics. The evidence that the continental plates moved and were not static began to pile on in the early 20th century.
WebbPerhaps the most dramatic example of the potential impact of plate tectonics on life occurred near the end of the Permian Period (roughly 299 million to 252 million years ago). Several events contributed to the Permian extinction that caused the permanent disappearance of half of Earth’s known biological families. The marine realm was most … WebbHis theory provoked much debate in scientific circles, because although there was some evidence of continental movement, there was no clear mechanism to drive plate movement. It took more than 50 years and the collection of a large body of evidence for broad acceptance of what we now refer to as plate tectonics theory (ACSES037).
