What is relative age dating of rocks
ANSWER: Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.This technique does not give specific ages to items.It only sequences the age of things or determines if something is older or younger than other things.Some types of relative dating techniques include climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.Ice core sampling normally uses the assumption that the ring bands observed represents years.One known example where this assumption was used is very misleading.The most obvious feature of sedimentary rock is its layering.This feature is produced by changes in deposition over time.
For example, rocks of the Phanerozoic eon are found on top of rocks from the Proterozoic eons therefore rocks of the Phanerozoic are younger than rocks of the Proterozoic.This theory held that the past was the key to the future and that processes that formed the layers were the very slow processes that we see forming layers at the bottom of the ocean today. Until Lyell successfully convinced scientists that uniformitarianism was the correct theory, it was believed that the worldwide flood and other catastrophic events were primarily responsible for the formation of the geologic layers and that they didn’t represent long ages.Later, when radiometric absolute dating methods were developed, they still were not applicable to sedimentary layers.Consequently, today the dates assigned to the “standard geologic column” are still based upon Lyell’s assignment where index fossils are used to date the rocks and the rocks are used to date the fossils. Today, it is not surprising that many geologists are rejecting uniformitarianism and embracing catastrophism again.There is much evidence that refutes uniformitarianism. Helens demonstrated that rapid deposition and rapid canyon erosion are a fact. Also, when life forms die they only become fossils when they are buried rapidly. Polystrate tree fossils that extend through multiple layers are common. Consequently, the uniformitarianism model, along with the age assignments of the geologic column, is in doubt. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.
With out individual time stamps the process of dating these structures could become extremely difficult.
