Continental Drift
Earth Science
| Term | Definition |
|---|---|
| Alfred Wegener | Came up with the Continental Drift Theory, his theory was rejected by many other scientists, he did not know how the continents moved |
| Continental Drift | The idea that Earth's continents moved apart from a single large continent called Pangaea |
| Fossil Evidence | Fossils of the same species were found on separate continents and nowhere else, these plants or animals would have had to evolve independently or swim these distances, fossils found didn't fit the climate; palm tree leaf fossils were found in Alaska |
| Glacial Evidence | Glacial deposits formed 300 million years ago are found in Antarctica, Africa, South America, India and Australia, Scratches on rocks show the ice flowing from the glaciers came from a single point, evidence of glaciers are found in warm climates today |
| Pangaea | A Super Continent, began to break apart about 175 million years ago, there were probably other super continents before Pangaea |
| Laurasia and Gondwanaland | Gondwanaland separated from Laurasia between 200-180 million years ago, this formed the northern and southern hemispheres |
| Continental Fit Evidence | The continents, particularly South America and Africa, fit together like puzzle pieces |
| Landform/Rock Layers Evidence | The Appalachian Mountains match well with those on the British Isles as well as other places, similar types of rocks and similar ages of rocks were found in different places, the coal fields in North America and Europe match up |
