Wegners 4 proofs
- Continents appear to fit together like a jigsaw puzzle
- The same animal fossils are found on separate continents, animals couldn’t swim across the ocean meaning the continents had to be connected at one point
-there are mountains and rock of similar structure and age found on different continents - Ice sheets once covered parts of Africa, Australia, South America, and India. These places are too close to the equator for ice sheets to form
