Theory of Continental Drift*- The 7 major continents were once

Evidence of Continental Drift*

Fossils – Similar fossils found on different continents.Climate – Climate change shows tropical plants in Greenland and glacial streaks in South Africa.Rocks – Similar rocks and formations on different continents.
