What clues provide evidence to the theory? | Many, but the first was the shape of the continents |
Explain how ROCKS can provide evidence for continental drift, and where in the world is this evidence? | Rocks of similar age and type were found on multiple continents. |
Explain how CLIMATE can provide evidence for continental drift, and where in the world is this evidence? | Grooves from glacial movement are found on continents/land masses that are too warm to have ice today, suggesting that they were once somewhere else on Earth. |
Explain how FOSSILS can provide evidence for continental drift, and where in the world is this evidence? What types of fossils have been found? | Both plant and animal fossils can be found across multiple continents. These creatures were unable to move freely across oceans, so it suggest that the continents were once adjoined. |
How quickly are the continents moving? | Very slowly….only a few cm per year. |
