Making this processes even more difficult is the fact that due to plate tectonics some rock layers have been uplifted into mountains and eroded while others have subsided to form basins and be buried by younger sediments.

With out individual time stamps the process of dating these structures could become extremely difficult. This feature is produced by changes in deposition over time.

The matching rock layers were deposited at the same time, so they are the same age. This process requires much more sophisticated relative dating grand canyon analysis and, although other processes have been developed, often utilizes the decay rates of radioactive isotopes to determine the age of a given material. Using this process geologists are able to assign relative dating grand canyon ages with known degrees of error to specific geologic events. Here, a vertical mile of the Grand Canyon has been exposed by erosion. The darker pavement was added later to cover up the lighter pavement that was cracking some cracks are visible directly behind the white ruler, which is shown for scale.
