Unit 4 Lesson 3 Part I

Scientists recently discovered that rocks collected from the Franklin Mountains in West Tests 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 of--

• coastal erosion

• plate tectonics

• ocean currents

• glacial melting
