Storyboard Text

  • Using sonar technology, we can map the mid ocean ridges.
  • I also found that when seafloor spreading occurs at mid ocean ridges, the new magma creates rock that pushing aside old sediment, widening the ridge.
  • There is also mountain evidence to show that Pangaea existed.
  • Mountain ranges on different continents have matching layers of rock sediments and perfectly align with each other, proving they had been one mountain range at some point.
  • There has also been plant fossils otherwise known for being in hot climates found in colder areas of the world.
  • Together, our evidence proves Pangaea was one super continent on Earth .
