Which term is defined as the process of determining the age of an object using the half-life of one or more radioactive isotopes?

• Radioactive Decay

• Carbon-14

• Absolute Dating

• Radiometric Dating

What is the primary difference between relative dating and absolute dating?

• Relative dating determines the exact age of a fossil, while absolute dating estimates the age.

• Relative dating estimates the age of a fossil based on its position, while absolute dating determines the exact age.

• Relative dating uses radioactive isotopes, while absolute dating uses fossil position.

• Relative dating is more accurate than absolute dating.
