However, since environments change over time, this is not a perfect way of determining geologic age.Unconformities represent a break in the relative time scale.By studying relative dating, you prepare yourself to make your own insights about different kinds of ancient environments and biomes on the APES exam.

Faunal succession can be used to chronologically put a group of animals and plants together and give greater detail to the history of the Earth.

Faunal succession is also used to compare fossils of organisms in different areas on the Earth.

Unlike absolute dating, relative dating does not assign specific years to individual events.

Instead, it seeks to establish which actions occurred where in a sequence of geologic events.

They occur where layers of rock were either eroded away or never deposited and cemented in the first place.

Sometimes there is evidence that an unconformity has occurred; other times, there is no way of knowing if there is a break in the relative time scale.Most fossils occur beneath water because these conditions most commonly occur in and around water.These necessary conditions also make it highly likely that fossils will form in sedimentary rocks, which is part of why fossils are so important in relative dating.The foreign object is thus older than the sedimentary rock because it was there before the sediment that formed the rock.A simple way to remember this term is to think that an inclusion represents something being included in the rock that wouldn’t have been otherwise.Fossils are of special importance in relative dating because they help scientists understand the ages of certain rock formations, as well as what kinds of organisms lived together at the same time. First, the organism must be rapidly buried and remain buried over time.
