Explain how Wegener used ancient glacier evidence to support his continental drift hypothesis

How was he able to account for lush tropical environments in North America, Europe, and Asia during the same time period of glaciation as South America, Africa, and India?
What will be an ideal response?


Answer: Since Wegener was a meteorologist he was able to reconstruct ancient glacial environments by observing evidence of vast ice sheets (and possibly glacial till and striations) on the Southern Hemisphere continents. During this same time (300 million years ago) the Northern Hemisphere continents where positioned at higher latitudes near the equator, where many swamps and coal deposits formed.
