Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute. The techniques scientist need for absolute dating did not become available until the later half of the 20th century. Absolute dating uses clues, such as the emperor's face on a coin, to date an artifact.
