Relative dating earth layers
(Be as specific as you can, such as "between the Jurassic and Tertiary periods," or "Within the Triassic period.") This unconformity is in the Proterozoic Eon.5.Between which two rock layers (use the names of the rock layers shown on the diagram) does the unconformity occur? What evidence do you specifically see that allowed you to identify an unconformity at this location? Which of the three types of unconformities is this? In the sequence of geological eons, eras, or periods, where is the unconformity located?
In cases were disturbances are suspected, geologists will have to determine what the original layering was by attempting to date the rocks.When geologists study layers of rocks, they get a glimpse of the past.Determining the precise way that sedimentary rocks have layered throughout time gives them insight into how natural events have occurred.In Part 2 you will use the principles of relative dating to determine sequences of geological events as indicated by the layers and structures in the rocks.Part 2 ends with an application of the principles of relative dating to the rocks of the Grand Canyon.
