Cross-continental Geological Formations

Since Wagner proposed the theory of continental drift, scientists have been searching for evidence to support his hypothesis. Building on the last piece of evidence discussed, continental shapes, cross-continental geological formations is further proof that once the world may have been joined as once super continent, and has slowly drifted apart to what the land is like today.

Geologists have discovered rock evidence in the form of several mountain belts that end at one coastline, and reappear on another continent. In these situations the age and type of rock match, as well as similar in structure.

A perfect example of this is the Appalachian Mountains that run along the eastern side of North America and end at the coast of Newfoundland. Geologists have found mountains that are similar age and structure to those of the Appalachian Mountains, are found in the British Isles and Scandinavia. When the continents are put together as Pangea, the mountains form an almost continuous belt.
