Relative Age
* NEW NGSS website is now available @ http://nextlevelsci.weebly.com *
How can we analyze and interpret data from index fossil records and the ordering of rock layers to infer the relative age of rocks and fossils?
Does this look like your room? Have you ever tried to find something you used a while ago and couldn't find it? Where would you look for it? On the top or on the bottom of that pile!? If you said the bottom, you understand the law of superposition. Scientists use this same logic along with many other techniques in an attempt to accurately date the age of rocks, fossils and the Earth.
