* Coal formation: Coal forms from ancient plant matter accumulating in swampy environments. While the presence of coal might indicate a past tropical environment, it doesn't directly connect to the idea of continents moving.
* Wegener's evidence: Wegener's theory of continental drift was based on a different set of observations:
* Matching coastlines: The shapes of continents, particularly on the Atlantic side, fit together like puzzle pieces.
* Fossil distribution: Identical fossils of ancient animals and plants were found on continents now separated by vast oceans.
* Geological formations: Matching rock types and mountain ranges were found on continents now separated.
* Climate evidence: Evidence of ancient glaciers in tropical regions, suggesting continents were once in different positions.
Coal, while interesting, doesn't directly link to the movement of continents. It simply points to past climate and environmental conditions.
