A radiometric dating technique that measures the ratio of the rare earth elements neodymium and samarium present in a rock sample was used to produce the estimate also, by extrapolating backward in time to a situation when there was no lead that had been produced by radiogenic processes, a figure of about 46 billion years is obtained. Q how do you explain the results of radiometric dating which say the earth is billions of years old, and the bible's account of creation. Radiometric dating how radiometric dating works in general why methods in general are inaccurate why k-ar dating is inaccurate the branching ratio problem.

Radiometric dating: result has come from radiometric age dating of the samples early attempts at calculating the age of the earth. Layers in glaciers show a history much longer than 10,000 years, and radiometric dating places the formation of the earth at 45 billion years light from galaxies is reaching us billions of years after it left, and the expansion rate of. When faced with this obvious discrepancy, evolutionists sometimes backpedal by saying that although the radiometric dates may not be perfectly accurate, even 40 million years is much older than 6,000 years, so the radiometric ages still prove the earth is old.

Age of the earth so far scientists which are firmly grounded in physics and are known collectively as radiometric dating the best age for the earth comes. Radiometric dating is a technique used to date materials such as rocks or carbon in addition to the ages of earth, moon, and meteorites. If a date obtained by radiometric dating does not match the assumed age from the geologic column, the radiometric date will be rejected the so-called geologic column was developed in the early 1800s over a century before there were any radio. How science figured out the age of earth and almost a decade passed between the first use of radiometric dating and the discovery of isotopes.

Most scientists and many christians believe that the radiometric dating methods prove that the earth is 45 billion years old the textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information far from being data, these dates are actually interpretations of the data. Radiometric dating provides an accurate method to know the age of the earth in 1896, the french chemist a henri becquerel discovered radioactivity, the process where materials decay into other materials, releasing energy.

Evidence for an ancient earth radiometric dating radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements. Before so-called radiometric dating, earth's age was anybody's guess our planet was pegged at a youthful few thousand years old by bible readers (by counting all the begats since adam) as late as the end of the 19th century, with physicist lord kelvin providing another nascent estimate of 100 million years. Before 1955, ages for the earth based on uranium/thorium/lead ratios were generally about a billion years younger than the currently popular 45 billion years the.

Radiometric dating has been used to determine the ages of the earth, moon, meteorites, ages of fossils, including early man, timing of glaciations, ages of mineral deposits.

How do scientists determine the age of the most widely known form of radiometric dating is carbon-14 this supports the current idea of the earth's age. These observations give us confidence that radiometric dating is not trustworthy most estimates of the age of the earth are founded on this assumption. Start studying earth science review learn vocabulary geological evidence of the age of the earth includes _____ radiometric dating of rocks (ans) fossil. Determining the age of rocks and fossils by: be determined through radiometric age dating or absolute age dating relative age of rocks earth science. Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes learn about.

Clocks in the rocks moon rock dating the ages of rocks returned to earth from the our best clues to the age of the moon are the radiometric dates. Radiometric dating has several problems: it makes assumptions (guesses) that we cannot possibly prove it has given very wrong dates for rocks that we know the age of for instance, it dated a known 11-year-old rock to 05-28 million years and a known 70-year-old rock to 027-35 million years. Uranium-lead radiometric dating involves using uranium-235 or uranium-238 to date a substance's absolute age this scheme has been refined to the point that the error margin in dates of rocks can be as low as less than two million years in two-and-a. The age of the earth is approximately 454 ± 005 billion years (454 × 109 years ± 1%) this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples. Scientists can select from many techniques of radiometric dating to determine the age of artifacts as well as the age of earth itself radiocarbon dating is used for dating once-living matter less than 40,000 years old, like wood and charcoal.
