Mountain chains in Northern Europe and West Africa match the Appalachian Mountains in terms of their ages and sequences of rock layers that make them up. In 3-5 sentences, analyze these observations, and explain what conclusion can be drawn from them.
1 answer
The observation that mountain chains in both Northern Europe and West Africa share similar ages and sequences of rock layers with the Appalachian Mountains suggests the presence of a geological connection between these regions. It implies that these mountain chains were likely part of a single ancient mountain range that existed millions of years ago and has since been separated by tectonic activity. This supports the theory of continental drift and the existence of supercontinents like Pangaea.
