In many ways relative dating is easier and quicker than radioactive dating but radioactive dating is a much more accurate way. Relative dating uses material such as rocks and fossils and attempts to place that material in a certain time based on where it was located and the rock around it. The time where the rock or fossil came from is based on times like the Jurassic period and other sections like that. Geologists use cross cutting as a method of relative dating by determining which rock sections came from where then putting all rocks and fossils found in that area into one group. The layers are like a sandwich with the top bread being the youngest group and the bottom bread being the oldest group. This is an example of The Principle of Superposition. As species have come and gone many have left behind fossils and remains from certain times but them seem to disappear in another while others suddenly seem to pop up with no records of fossils from before
