Storyboard Text

  • Then, the Colorado river poured into a basin which formed a giant lake.
  • A long long time ago...
  • There was a mountain range the size of the Himalayan mountains. That erodied away. This was where the Grand Canyon is now.
  • Then oceans came and dropped of different sediment which created different layers
  • The tectonic plates pushed the plain straight up to create a plateau.
  • The water and the rocks that the water carried carved the canyon 1 foot per 1000 years!
  • The lake then rose and spilled over the plateau. The water was so powerful that it carved the canyon.
