Radioactive emissions consist of Alpha, Beta and Gamma radiation. Taking K-Ar as an example, the sample must be selected from a rock believed to be representative of the geological process being investigated. The general rule with radiometric dating especially radiocarbon is that you can date stuff back to times the half life of the isotope.
One is spontaneous fission, which is a form of natural radioactive decay. What is the Law of Original Horizontality? Have a crack at K-Ar Dating in a reference such as wikipedia.
How organisms change over a period of time What type of rocks contain fossils? This can also occur in nature, but it is unusual for it to happen.

We must relate them to other layers surrounding the sedimentary layer. What is the process where minerals replace all or most of an organisms body parts? The circumstances of the object may allow one to say that one object is older than another without being able to assign a particular age to the objects.
Other radiometric decays use the actual signature of the decay process as the measure of that event.
For the ocean, this is done by U-Th dating aragonitic deep sea corals then measuring their radiocarbon content. There is a third more rare decay.
