Wegener was able to use evidence from climate change so as to be able to give support his theory in the sense that he used explained that an island in the Arctic Ocean do contains fossils of tropical plants.
Base on the theory that continents were once connected help in explaining the glacial striations however, if the continents always occupied their present-day positions, it will be hard to explain pattern of glacial striations since the theory of continental drift theory is based on the rotation of the Earth.

It should be noted that Wegener suggested that rotation of the Earth that come as a result of how the continents shift towards and apart from each other.
