Concept of radiometric dating
Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.So, we rely on radiometric dating to calculate their ages.Karen Alonzi-Van Gundy has twenty-one years experience as an elementary school teacher in Jefferson County, Colorado.She is involved in teacher education through Colorado State University and the Colorado School of Mines.Did you know that you can be a Christian, and believe that the earth is billions of years old?
You can even believe in evolution and be a Christian.
As Director of the Denver Earth Science Project at the Colorado School of Mines from 1989-1997, she had opportunity to develop relevant earth science curricula in partnership with geoscientists working in the Denver area. in Micro-paleontology from University College Swansea, University of Wales.
Diana Scheidle Bartos is a gifted science education writer who has a very strong science background in geology and chemistry. He is currently Associate Keeper of Paleontology at The Natural History Museum, London.
Radiometric dating is sometimes referred to as radioactive dating.
In fact, you might like this term better, because the dating method relies on the known decay rate of radioactive isotopes.
Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.
