Discussion: Evolution of the Earth - The Importance of Geological Time
Select a feature located within your national park, and give an estimate of its age using both relative and numerical terms. Describe a possible fossil that you would expect to find there and what time period it represents. Mark this feature on your map within Google Earth. Then create a folder and add this and your previous placemarks from Modules Two and Three into the folder to begin creating your tour.
Select and briefly discuss an example of what conditions were like in your national park during one of Earth's previous eras. Include your updated Google Earth map in your post.
