Storyboard Text

  • Hey Puggly! I was wondering if you could tell me how the earth formed again. I forgot.
  • Of course! It is my favorite subject! Ask any questions you would like. 
  • Did the earth form along with the solar system?
  • Why yes it did! Billions of years ago, a supernova explosion occurred that created particles and clouds of dust orbiting around the sun.
  • Interesting.
  • Then, when all of those clouds of dust cooled down, the grains of minerals stuck together and formed small pieces of rock.
  • Wow! Thats so cool! What next?
  • Well, some of the pieces of rock floating in space collided over the next couple million years, forming larger rocks that kept growing and eventually grew into planets, such as earth.
  • Was the earth hit with a lot of objects?
  • Yes, it was. As the earth grew, its gravitational pull did as well. The earth started attracting bigger and bigger objects that increased the earths size with each impact.
  • How long did it take for earth to get so big?
  • It took the earth roughly 30 million years for it to reach its present day size. And while that may seem like forever, its nothing compared to the fact the earth was created over 4.5 billion years ago!
