Question

1. studying the movements of plates is a critical component of the continental drift theory. describe three other pieces of evidence that have been found to support the idea of continental drift.

Explanation:

1. Fossils of identical species (like Mesosaurus, a freshwater reptile) are found on continents now separated by oceans, indicating the landmasses were once connected.
2. Rock layers and mountain ranges (such as the Appalachian Mountains in North America and the Caledonian Mountains in Europe) match in age, composition, and structure, showing they formed as a single range before continental separation.
3. Glacial deposits and striations (scratches from ice) are present in areas that are now warm, like southern Africa and India. This implies these regions were once near the South Pole, and continental drift moved them to their current tropical/temperate positions.

Answer:

1. Matching fossil distributions across separated continents
2. Corresponding rock formations and mountain chains on different continents
3. Paleoclimatic evidence (e.g., glacial deposits in tropical regions)
