Law of relative dating
Absolute dating can be helpful when there is some uncertainty about whether all features of the rock are present.
Inclusions occur where a sedimentary rock forms around a foreign object.
Since many plants and animals have large habitats, this can be very useful in helping to date sediment layers of interest.
Fossils are any preserved remains or traces of an organism that previously lived.
By studying relative dating, you prepare yourself to make your own insights about different kinds of ancient environments and biomes on the APES exam.
Relative dating is the process of establishing a sequence of historical events and relative ages of rocks by looking at sedimentary rock formations and their features.
This can be a challenging concept to understand, but if you imagine a basin where sediment is deposited, this principle states that the sediment will be equally deposited in this area until there is no more sediment or until the sediment reaches the edge of the basin or another barrier.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.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.
