Plate Tectonics Evidence
By Alex Freeman
Plate Tectonics
The earth’s crust and upper mantle are broken into sections called plates.Plates moved around on top of the asthenosphere or the mantle like rafts. Oceanic plates: plates below the ocean. Continental plates: plates below the continents
Continental Drift
A map of the continents inspired Wegener's quest to explain Earth's geologic history. Trained as a meteorologist, he was interested by how Africa's and South America's shorelines fit together. Wegener then assembled an impressive amount of evidence to show that Earth's continents were once connected in a single supercontinent and slowly drifted apart.It would have been physiologically impossible for Mesosaurus to swim between the continents. This suggests that South America and Africa were once joined.
Fossil Evidence
Rock Evidence
Caledonian Mountain range is in the Scottish Highlands. The Appalachian Mountain range is in the eastern US. This is another way that proves that the continents where once together.
