Law of relative dating

Now all of a sudden the big tower of cookies running through the middle of your cake is the youngest feature, as the other three layers in order for it to be there.Your 3 layers will consist of a chocolate cake, a vanilla cake, and a cheesecake, because you're crazy and your cake doesn't have to conform to standards. On your plate, you put the chocolate cake on bottom, or the first layer. Then vanilla and cheesecake are the second and third oldest, respectively. Now that I've gotten you all hungry for cake and cookies let's talk about rocks instead.This aspect of Werner's model was useful for explaining the origin of tilted sedimentary rocks.(dark brown) Flat lying sedimentary rocks were eventually precipitated.

The classic type is the angular unconformity of which Thornton Force in Ingleton and Combs Quarry, Foredale are perhaps the best known local examples.If the geological record was 100% complete and there were no breaks in sedimentation, the stratigrapher's job would be an easy one.However, breaks in sedimentation do occur and when this happens, geologists' refer to this missing strata as an unconformity.(light brown) Next, fossil-rich sedimentary rocks were precipitated.These rocks are tilted due to deposition on the non-horizontal surfaces of primitive rocks.
