The map of the world today, is very different to what the world looked like 200 million years ago. For a long time many people believed that the continents have always been in the same place. It was not until 1915, when Alfred Wegener proposed the theory of continental drift, did his investigation open a gateway to bigger possibilities. The theory of continental drift suggested that the continents had once been joined together, split apart due to plate tectonic movement and moved slowly around the surface of the Earth.
The idea of continental drift challenged many scientists. However, as scientists add to the theory or discover new evidence, they became closer to explaining continental drift.
Evidence supporting continental drift:
- Continental shapes
- Cross-continental geological formations
- Fossil distribution
- Age of ocean rocks and sediments
- Direct measurement
- Glacial Deposits
- Palaeoclimates
- Glacial Deposits
- Palaeoclimates
Good intro Dianne, we will look at other evidence of paleomagnetism and polar wandering later to add to this.
