Advantages and disadvantages of relative dating Free adult no sign up flirt chat

The earth precesses (wobbles like a spinning top) around the sun in a series of cycles.These cycles affect sunlight and hence long-term can form layers in rock.In some cases these astronomical cycles in rock appear to have been laid down over some 25 million years (and radiometric dating puts the absolute age of the rock at some 200 million years).Dating Anomalies Here we outline a few dating methods or 'clocks' that present a dating anomaly when referenced to the widely accepted OE age of 4.6 billion years. At the outset we note C-14 cannot be used to directly date the earth for the simple reason that the unstable C-14 isotope has a half-life of just 5,730 years.But YE scientists point out some anomalies in relation to C-14 and a very old earth.For instance, measurable amounts of C-14 have been found in fossil material, such as coal (traditionally Carboniferous period c300 mya).Ice cores from Greenland and Antarctica show annual layers (varves) and can be traced up to about 40,000 years before the layers become too thin due to compaction.Similarly, annual lake sediments can be used to estimate relative age and conventional interpretation for the Green River varves suggests they have been formed over some 20 million years.

Astronomical cycles can also be used to measure relative age.These estimates give 4.4-4.5 billion years for moon rock, and 4.54 billion years for iron metreorites.These techniques utilize the physical parameters of the earth, such as ice cores, annual lake sediments, and astronomical cycles.And OE Christians (theistic evolutionists) see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating - A Christian Perspective.This is the crucial point: it is claimed by some that an old earth supports evolutionary theory and by implication removes the need for biblical creation.The crucial point here is: if YE theory can be established scientifically, then macroevolutionary theory falls!Accepted Dating Methods Here we outline some dating methods, both absolute and relative, that are widely accepted and used by the scientific community.Absolute dating supplies a numerical date whilst relative dating places events in time-sequence; both are scientifically useful.This is based upon the spontaneous breakdown or decay of atomic nuclei.One problem with earth dating is that the original earth surface is assumed to have eroded long ago.But assuming the earth was formed at the time of the rest of our solar system, then recovered moon rock and meteorites can also be used to estimate the age of the earth.

Since relative dating can easily be verified by superposition the younger bed over the older one, intrusion the intrusive being younger than the intrusive rock, and use of index fossils younger fossils in a rock layer make that layer younger than another containing older fossils, relative dating can be.
