A Changing Earth

Theories that Earth's surface has evolved over geologic time due to natural processes are well supported by physical evidence. Listed below are some of the most convincing pieces of evidence for continental drift:

1) Physical evidence that ancient glaciers once covered corresponding parts of now-separated continents

2) Similar fossils found in corresponding regions of now-separated continents

3) Rocks with similar chemistry and similar age found on separate continents
