Lava (properly called magma before it erupts) fills large underground chambers called magma chambers. A number of processes could cause the parent substance. To be depleted at the top of the magma chamber, or the daughter product to be enriched, both of which would cause the lava erupting earlier to appear very old according to radiometric dating, and lava erupting later to appear younger. Radiometric dating works by determining the ratio of the number of isotopes of an element and the number of isotopes the element it turns into over time.
Since the rate at which certain elements decay and turn into different elements is understood, scientists are able to calculate the. Age of substances. The former argument is flawed because many radiometric dates are broadly supported by other estimates of change, such as tree rings and varved sediments for radiocarbon (with some discrepancies, but still leaving the Earth far more than 6,000 years old).
Students may also be aware that bad assumptions and contamination can result in inaccurate radiometric dates. This is very true.

Then I found out that Sited was planning a major project on radiometric dating. So, I switched to other challenges, since ICR was .
There are many assumptions behind radiometric dating, but there are three main ones. Uniformitarian scientists assume (1) the initial isotope amounts are known, (2) the decay. Rate has remained constant at todays rate, and (3) the sample has remained in a closed system for millions and billions of years. Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.

Few people who think that radiometric dating proves the earth is billions of years old really understand the underlying assumptions. Radiometric dating methods rely upon circular logic, such as.

Naturally-occurring radioactive materials break down into other materials at known rates. This is known as radioactive decay.
