Which method estimates the time of fossils based on radioactive carbon amounts and types? Relative dating Absolute dating geologic dating Molecular clocks

## Step 1<br />The question is asking for the method that estimates the age of fossils based on the amount and type of radioactive carbon. This is a description of absolute dating.<br /><br />## Step 2<br />Absolute dating, also known as radiometric dating, involves the use of decay rates of radioactive isotopes to date rocks and fossils. This method provides a numerical age or range in contrast with relative dating which provides only an order of events.<br /><br />## Step 3<br />The other options, such as relative dating, geologic dating, and molecular clocks, do not specifically estimate the age of fossils based on the amount and type of radioactive carbon.
