Compare and contrast relative dating and radiometric dating
Once something dies, it ceases taking in new carbon-14, and the existing carbon-14 within the organism decays into nitrogen at a fixed rate.
Scientists measure the proportion of carbon-14 left in the organism to determine its age.
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.
Relative dating helps determine what came first and what followed, but doesn't help determine actual age.
These use radioactive minerals in rocks as geological clocks.The age of the earth can be estimated by taking the first five days of creation (from earth’s creation to Adam), then following the genealogies from Adam to Abraham in Genesis 5 and 11, then adding in the time from Abraham to today.Adam was created on day 6, so there were five days before him. So a simple calculation is: At this point, the first five days are negligible.Relative dating determines the period of time from which an object come from based on technology, soil, anthropology, etc.Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods.
