Explain the differences between relative dating and radiometric dating, paul jones
How are positive and negative ions formed? What are the difference between ancient geology to modern technology? What happens when a gas is compressed? The radiometric techniques that give absolute dating estimates are based on radioactive decay of elements such as uranium.
The primary difference in relative dating and absolute dating is that absolute dating assigns an actual time or age to an event or object. Knowing that the carbon 14 has a half life of 5, years allows the estimation of the age of the object based on the fraction of carbon 14 remaining. This figure is in good agreement with the age of meteorites and the age of the Moon as determined independently.
The law of included fragments is a method of relative dating in geology. Faults are younger than the rocks they cut; accordingly, if a fault is found that penetrates some formations but not those on top of it, then the formations that were cut are older than the fault, and the ones that are not cut must be younger than the fault.

If an archaeologist is studying past civilizations, the archaeologist may be able to say that in a particular location the ruins of once civilization were found to have been build on another and so the layers unearthed in an excavation convey the sequence of historical occupations without revealing the actual dates.
Nevertheless, they can provide an abundance of useful information. A similar situation with igneous rocks occurs when xenoliths are found. In many respects they are analogous to fluid inclusions. Photo courtesy of Rod Benson, www.
