Absolute dating numerical age method
Very often historical evidence is found in layers and older layers are further down that the top layers.
For example: If an archaeologist is studying past civilizations, the archaeologist may be able to say that in a particular location the ruins of one civilization were found to have been built on another and so the layers unearthed in an excavation convey the sequence of historical occupations without revealing the actual dates.
Your welcome for helping you with Biology Homework.... Both are attempting to get information on the history of events.
Relative dating, meanwhile, measures the order of past events, without determining their absolute age.
Similarly, relative dating is done by paleontologists who find layers of fossils.
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.
Absolute dating tells when the fossil was formed, relative dating compares fossils to other fossils, some fossils cannot se absolute dating so they have to use both relative and absolute dating together.
Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology.
Both relative dating and absolute dating are procedures used to give temporal characteristics to a sequence of events.
