How did wegener explain the existence of glaciers in the southern landmasses and the lush tropical swamps in North America Europe and Siberia?

Answer 1

Wegener explained the existence of glaciers in the southern landmasses and lush tropical swamps in North America, Europe, and Siberia through his theory of continental drift. He proposed that these regions were once part of a supercontinent called Pangaea, which allowed for climate zones to shift over time. As the continents drifted apart, areas that were once near the poles became tropical, while regions that were once warm moved to colder climates, leading to the formation of glaciers and swamps in their respective locations. This movement accounted for the geological and paleoclimatic evidence observed in different regions.
