Relative dating geology methods single parent guide to dating
For instance, if we find a fossil bone below the strata 3 rock level shown above, we assume that the animal most likely lived at a time before that layer was formed.However, we must be careful to note whether or not the fossil comes from the mixed strata zone of the filled in hole..Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.As the name implies, relative dating can tell which of the two artifacts is older.This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.It implies that relative dating cannot say conclusively about the true age of an artifact.
Wind and water erode strata and some areas are uplifted or even tilted.It is possible to tell the number of years ago a particular rock or archeological site had been formed.Two broad categories of classification methods are relative dating and absolute dating.However, archeologists still require further information to find out the items that are oldest and those that are youngest in the order.
It is left for absolute dating to come up with the precise age of an artifact.
These processes result in All of these processes confuse the stratigraphic record.
