Scientists recently discovered that rocks collected from the Franklin Mountains in West Texas and rocks collected from mountains in eastern Antarctica were exactly the same age. Further research showed that the rocks were chemically and geologically the same and came from the same magma source. This discovery provides evidence that supports one of the below topics.

The evidence supports the topic of Plate tectonics. The similarity in age, chemical composition, and geological characteristics of the rocks from different locations indicates that they may have once been part of the same landmass before being separated by tectonic processes.
