Final answer:
Chronometric dating techniques allow archaeologists to establish a specific age for fossils or organic materials, such as through radiocarbon dating. These methods use the decay of carbon-14 to determine when an organism died, within a more precise time frame than relative dating techniques.
Step-by-step explanation:
Chronometric dating techniques used by archaeologists help establish a more specific age for a fossil or something organic. This type of dating, also known as absolute dating, relies on the chemical or physical properties of objects to determine their age. The most commonly known method is radiocarbon dating, which measures the remaining carbon-14 in organic materials to calculate when the organism died. Unlike relative dating that provides a sequence of events without an exact date, chronometric dating provides a more specific age range for the samples. Proper collection and sealing of specimens are crucial to prevent contamination and ensure accuracy of the measurement.
Applying a variety of dating techniques gives archaeologists a stronger evidence base for determining the specific period of time to which an archaeological site belongs. By correlating multiple methods, such as combining absolute dating with relative dating methods, a more comprehensive understanding of the geological age and rate of speciation of organisms is achieved.
