Radiometric dating high school offers online dating services

Radiocarbon dating was used to identify a forged painting based upon the concentrations of carbon-14 detected on the canvas within the atmosphere at the time that the picture was painted.So, to sum this all up, radioactive dating is the process scientists use to conclude the ages of substances dating back several to many years ago by using the isotopes of elements and their half-lives.

An isotope is a variation of an element based upon the number of neutrons.

The disintegration of the neutrons within the atom of the element's nucleus is what scientists call radioactivity.

Remember, isotopes are variations of elements with a different number of neutrons.

The half-life is reliable in dating artifacts because it's not affected by environmental or chemical factors; it does not change.

These are both isotopes of the element carbon present in a constant ratio while an organism is living; however, once an organism dies, the ratio of carbon-14 decreases as the isotope deteriorates.

Radiocarbon dating can only be used to date items back to as far as about 50,000 years old.Try it risk-free Ever wonder how scientists concluded the age of the earth to be about 4.6 billion years old or how geologists determined the ages of caverns, rocks, volcanoes, the Himalayas, or even the age of Pompeii bread?Well, scientists are able to answer all of these wondrous questions and more by use of a process called radiometric, or radioactive, dating.Radioactive dating enables geologists to record the history of the earth and its events, such as the dinosaur era, within what they call the geologic time scale.Radioactive dating uses the ratios of isotopes and their specific decay products to determine the ages of rocks, fossils, and other substances.As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more.
