Explain relative dating of fossils profile dating services

Absolute dating of rock is achieved by radiometric dating techniques.

Relative dating is achieved by determining the position of rock in strata, and the appearance of certain index fossils.

The other is absolute dating, which measure the decay of carbon atoms.

"Radiometric dating" gives you an exact date of formation for a layer or a rock, even if you don't have another layer or rock to compare it with.

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 is determining the relative order of past events, without necessarily determining their absolute age. *note; even if the age is wrong it would still be classified as absolute time Absolute dating is the process of determining an approximate computed age in archaeology and geology.

The difference between Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of the evolved fossils Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of the evolved predators.

Relative dating-comparing fossils related to how old other fossils are in the same sample of rock.

This index fossils generally, occur in relative sequence each indicating a different age period.
