On the other hand, in absolute dating, methods like radiometric dating, carbon dating, and trapped electron method are used. For geologists , it is similar. People fall below this line and do not have enough money to buy food, shelter, clothing etc.\

Before radiometric dating or other elements of absolute dating like counting tree rings it was difficult to determine the actual age of an object. Long Answer: Sciences what is relative dating and absolute dating as geology, paleontology and archeology are very interested in identifying the age of objects found and these scientists sometimes use both relative dating or con dating to characterize the age of the objects they study. Before radiometric dating or other methods of absolute dating like counting tree rings it was difficult to determine the actual age of an object. Tools like radiometric dating allow some samples to be assigned a certain age to within some accuracy. By deducing which fossils are formed in the sequence of time, the periods when the particular fossilized entities existed can be arranged in order without the actual dates of when the fossils were laid down. July 2013 Thermoluminescence Thermoluminescence testing also dates items to the last solo they were heated. The circumstances of the object may allow one to say that one object is older than another without being able to assign a particular age to the objects. As the word relative tells that defining the object with respect to the other object, it will be prime to mention here that actual numerical dates of the rocks or sites are not known in this type of dating. Relative techniques are of great help in such types of sediments. Basically, fossils and rock found in lower strata are older than those found in higher strata because lower objects must have been deposited first, while higher objects were deposited last. The search for something only ends once the whole timeline becomes known.

Narrow rings grow in cold or dry years, and wide rings grow in warm or wet years. Radiometric dating, based on known rates of decay of radioactive isotopes in objects, allows a specific age of an object to be determined to some degree of accuracy. Coins found in unearthing may have their creation date composed on them, or there might produce records depicting the coin and when it was utilized, permitting the site to get related to a logbook year. At first, there were not many methods of dating were available, but now with advancement in the technology, we mainly have two types of the techniques to ascertain ages of ancient belongings.\

**Dating techniques** - Original horizontality The states that the deposition of sediments occurs as essentially horizontal beds.\

In geology rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating which provided a means of absolute dating in the early 20th century, archaeologists and geologists were largely limited to the use of relative dating techniques to determine the geological events. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occur, it remains a useful technique especially in materials lacking radioactive isotopes. Relative dating by biostratigraphy is the preferred method in paleontology, and is in some respects more accurate. The Law of Superposition was the summary outcome of 'relative dating' as observed in geology from the 17th century to the early 20th century. The regular order of occurrence of fossils in rock layers was discovered around 1800 by William Smith. While digging the Somerset Coal Canal in southwest England, he found that fossils were always in the same order in the rock layers. As he continued his job as a surveyor, he found the same patterns across England. He also found that certain animals were in only certain layers and that they were in the same layers all across England. Due to that discovery, Smith was able to recognize the order that the rocks were formed. Sixteen years after his discovery, he published a geological map of England showing the rocks of different geologic time eras.
