How does the continental drift theory explain why the same landforms and vegetation exist on continent separated by kilometer of ocean?

Answer 1

The continental drift theory posits that continents were once part of a single supercontinent called Pangaea, which gradually broke apart and drifted to their current positions. This explains the similarity in landforms and vegetation across continents separated by oceans, as these regions were once connected and shared similar ecosystems. Geological and climatic conditions that shaped these features were thus distributed across the landmass before separation. As continents drifted apart, remnants of these shared environments became isolated, leading to corresponding similarities despite the oceanic barriers.
