the earth

Storyboard Text

  • i wonder how our earth was formed
  • it goes back a very long time , about 4.7 billion years ago .
  • scientist have believed the earth congealed from the cloud of dust and gases that also formed the sun and other planets .
  • the earth may have trapped some of those gases within its mantle , volcanic eruptions returned the gases to earths surface where gravity kept them from drifting apart .
  • the mixing of gases along with oxegan and other molecules added by life created the atmosphere we have today .
  • i understand now thank you mr.lopez
