Geologic Time...

Learn about the age of the earth and how we know through the links of this page.  Did you know the earth is over four billion years old?  How long do you think humans have been around?  Do some research and find out by using the links below the picture.

Use these first few resources to help you with the Geologic Time Scale Research -
  • Geologic Time Scale: Eons, Eras and Periods - I don't know much about this site, but it appears to have some good information. 
  • Geologic Time Scale - UCMP Berkley - This site includes more detailed information about the geologic periods.
  • fossils-facts-and-finds.com - This is another great site to get the information you need in research your geologic period.
  • Geologic Time Machine - This site contains information about different time periods in our geologic history as well as pictures of fossils found from those times.
  • Geologic Time Scale - This is from Enchanted Learning and has some godo information.
  • Encyclopedia - Geologic Time - There are some clickable links in the encyclopedia to brief information about the different time periods.
  • Fossils Through Geologic Time - You can look at some of the fossils found from different time periods. This could give you some great information for your research.
  •  Deep Time - an interesting site that looks at Earth's History using a clock.
​
The following links might help you get more information or are just interesting.

Geologic Time - What if there was a book that included all of geologic time?  This site gives you an idea of what that book would look like.

Geologic Time Chart - The Idaho Museum of Natural History put together this website to help train their docents and others about geologic time.

Stories from the Fossil Record - Fossils help us understand geologic time.  UCMP Berkeley does it again with this site.

Life Has a History - Another great webquest from UCMP Berkeley.

Geologic Time: Earth Floor - Here is information about geologic time.  Easy format.


What if the history of the earth could be shown in a calendar year?  Well, check out the video below to see what it would look like if our history were reduced to a year.
