Which of the following statements are evidence of Plate Tectonic Theory?

Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together.

Fossils tell us when and where plants and animals once existed. Some life "rode" on diverging plates, became isolated, and evolved into new species. Other life dispersed to new areas as continents reconnected, oceans narrowed, or chains of volcanic islands formed. Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement. This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwanan.

Similar geologic formations on different continents show historic land connections. Antarctica’s mountains are an extension of South America’s Andes. If Southern Hemisphere continents were reassembled into a single landmass, glacial remnants in Africa and India would realign.
