North America and Antarctica Were Attached to Each Other

Scientists have found the strongest evidence yet that North America and Antarctica were once connected.

The international team discovered that rocks collected from the Franklin Mountains in West Texas have the same chemical and geological properties – as well as the exact same composition of lead isotopes – as rocks collected from Coats Land, an area that was once part of the Antarctic continent south of the Atlantic Ocean basin.

How is that possible? When you look at a globe or examine a map of the world, everything pretty much looks familiar to us.
