Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give example of absolute age dating an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes. These break down over time in a process scientists call radioactive decay.

Although both relative and absolute dating methods are used to estimate the age of historical remains, the results produced by both these techniques for the same sample may be ambiguous. Geological specimens that are unearthed need to be assigned an appropriate age. To find their age, two example of absolute age dating geological dating methods are used. These are called relative and absolute dating techniques. Absolute dating, also called numerical dating, arranges the historical remains in order of their ages.
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word "absolute" implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history.

In the field of Geology, dating is an important term as it is a technique through which evaluation regarding the age and period about the fossil, remains, the archaeologists do valuables and artifacts. At first, there were not many methods of dating were available, but now with advancement in the technology, we mainly have two types of techniques to ascertain ages of ancient belongings. Relative Dating and Absolute Dating are two types of such techniques which are under practice to determine the age of the fossils, objects or civilizations. The relative dating is the technique in the Geology through which the age is determined with relation to the other objects. In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older. Contrary to this, absolute dating example of absolute age dating the technique, using which the exact age of the artifacts, fossils, or sites are ascertained. The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other. In relative dating the exact age of the object is not known; the only thing which made clear using this is that which of the two artifacts is older. Relative dating is a less advanced technique as compared to absolute dating. In relative dating, mostly the common sense principles are applied, and it is told that which artifact or object is older than the other one.

I really need help, What are some examples of Relative dating and Absolute dating? Well I'm trying to do a project and I need three examples of things that only apply to relative dating, two examples of things that only apply to both relative and absolute daing and three examples of things that apply to absolute dating.
Relative vs Absolute Dating. Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists. There are many methods employed by these scientists, interested in the old, to get to know the age of items. 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. 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.
