Contrast the usefulness of absolute and relative dating techniques
a metamorphosed igneous rock may give a crystallisation age of 500 million years and a metamorphic age of 400 million years indicating the metamorphism is younger than the igneous rock, which of course this would be self evident from the relative dating observation that the igneous rock was metamorphosed (since the igneous rock could not have been metamorphosed before it formed!) Both relative and absolute dating can be used to substantiate correlations: e.g. Relative dating is qualitative - i.e it can only say one thing is older or younger than another. Relative ages: Relative ages are based mainly on observed or inferred field relationships and stratigraphy/biostratigraphy, rather than laboratory measurements.If you truly believe and trust this in your heart, receiving Jesus alone as your Savior, declaring, "Jesus is Lord," you will be saved from judgment and spend eternity with God in heaven. Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists.
A layer that is higher is of later age than a layer that is lower in order.QUESTION: What is the difference between relative and absolute dating techniques?ANSWER: In relative dating, something is determined to be older or younger than something else without determining an exact age. Absolute dating is rather limited as to the materials that can be dated, and mostly (but with a few exceptions) only works on igneous and metamorphic rocks. Absolute dating is difficult, time-consuming, expensive, and relatively inaccessible.
