Relative dating is determining whether an object is older or younger than other objects or events.It doesnt give an exact age but a relative (or comparison) age. Each layer will be successively younger or more recent. Superposition is the principle that says younger rocks lie above older rocks in an undisturbed sequence.Erosion could also take a mineral or fossil out of position and place it in another layer, thus causing humans to incorrectly assume an older or different age. If you did it like many people, you based your sentences on what you know normally happens when you make a lunch.If the layers you're examining are very small, it can be hard to determine for sure which occurred first.
In terms of paleontology, if an earthquake occurs and moves a fossil to another layer of the earth, one would think that fossil is older or younger than it is. By burying our dead, we impose them into geologic layers that we, ourselves, did not actually live in.Because relative dating doesn't give you an absolute age, errors are much less common in comparison to absolute dating.However, forces that can disturb relative dating or at least make it more challenging include multiple geological processes occurring over a short period of time.Rather than putting them into a photo album they are stacked up in a box. If a scientist finds one of those fossils, they can then assume the age of the rock based on the age of the fossil.Where are the oldest pictures, by year, going to be in your stack? Often igneous intrusions will cut across layers of rock.Cross-dating can indirectly establish a date for artifacts and sites.
