Which of the following statements best gives an example of absolute age?(1 point)
The extrusion is younger than the rock layer below it.
The half-life of carbon-14 is 5,730 years
In horizontal layers of sedimentary rock, Rock layer A is older than Rock layer B.
I am older than my sister.
The half-life of carbon-14 is 5,730 years.
The statement "The half-life of carbon-14 is 5,730 years" best gives an example of absolute age.
The statement "The half-life of carbon-14 is 5,730 years" best gives an example of absolute age.
To understand how this statement represents absolute age, it helps to know what absolute age means. Absolute age is the actual age of a rock, fossil, or event in years. It is determined through scientific methods such as radiometric dating, which relies on the decay of radioactive isotopes.
In the given statement, the half-life of carbon-14 is mentioned. The half-life is the time it takes for half of the radioactive substance to decay. In this case, carbon-14 has a half-life of 5,730 years. This means that after 5,730 years, half of the original amount of carbon-14 will remain. By measuring the amount of carbon-14 remaining in a sample and comparing it to the amount of the stable carbon isotope, scientists can determine the absolute age of the sample.
Therefore, the statement about the half-life of carbon-14 represents absolute age because it refers to a specific number of years and a scientific method used to determine the age of substances.
