Investigation: Open this site in a new window (right click on the link and then select "Open in New Window"):

1. Identify at least three geologic processes represented in the images. [Step 1]

   
   

2. What evidence might indicate that the processes you described may also have occurred sometime in the past? [Step 1]

   
   

3. Which layers were deposited first and are therefore the oldest? [Step 3]

   
   

4. Which layers were deposited last and are therefore the youngest? [Step 3]

   
   

5. How might layers that were once horizontal come to be tilted like this? [Step 4]

   
   

6. What type of force was applied to these rocks to form folds? [Step 5]

   
   

7. *SKIP THIS QUESTION - IMAGE DOES NOT LOAD

8. Make a sketch of the layers on the front of the 3-D block. Then, number the layers from oldest to youngest. Next, use another sheet of paper to write a detailed description of the geologic history of the site. (Include information about which principles you used to deduce the sequence.) [Step 9]
   *You may use the reverse side of this sheet for your sketch

Extra. With any remaining time, please explore the following:

• Online Earth's History Quiz
• Observer how fossils can form
• Observe an animation showing the formation of an unconformity
