Why is it difficult to date sedimentary rocks using radiometric dating techniques?, Socratic

The first method is called relative dating. This considers the positions of the different rocks in sequence (in relation to each other) and the different types of fossil that are found in them. The second method is called absolute dating and is done by analysing the amount of radioactive decay in the minerals of the rocks.
