Question

Statement 1: Age of the fossils are determined by carbon dating method.

Statement 2: Radioactive isotopes of elements like carbon and potassium breakdown at unknown rate.

• A. Both statements are correct.
• B. Both statements are incorrect.
• C. Only statement 1 is correct.
• D. Only statement 2 is correct.

Answer 1

The correct option is C Only statement 1 is correct.

• Paleontologist determine the age of the fossils by using carbon dating method.
• This method uses radioactive isotopes of elements like carbon, potassium, uranium which decay at a known rate. This decay rate and amount of element left after decay is used to determine the age of fossils.
