The other three are Windy Gyle, Cushat Law and Bloodybush Edge.
The 2013 national Youth Risk Behavior Survey found approximately 10% of high school students reported physical victimization and 10% reported sexual victimization from a dating partner in the 12 months* before they were surveyed. Teens receive messages about how to behave in relationships from peers, adults in their lives, and the media. Risks of having unhealthy relationships increase for teens who: Dating violence can be prevented when teens, families, organizations, and communities work together to implement effective prevention strategies.

Until this century, relative dating was the only technique for identifying the age of a truly ancient object.By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.Carbon-14 is also passed onto the animals that eat those plants.After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.Sedimentary rocks are rarely useful for dating because they are made up of bits of older rocks.Uranium is present in many different rocks and minerals, usually in the form of uranium-238.Geochronologists do not claim that radiometric dating is foolproof (no scientific method is), but it does work reliably for most samples.It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for "young Earth" theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques.

I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.

Love-hungry teenagers and archaeologists agree: dating is hard.

But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.

his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale.

It is not about the theory behind radiometric dating methods, it is about their , and it therefore assumes the reader has some familiarity with the technique already (refer to "Other Sources" for more information).
