2 pieces of evidence Alfred Wegener used to prove his theory

1. Jigsaw puzzle fit between Africa and South. 2. Fossils of plants and animals on both sides. 3. Mountains similar in age and structures on both sides of the Atlantic. 4. Ice sheets covered Africa, India, Australia, and South America 250 million.
