Q. Consider the following statements regarding “carbon dating”:
1.Carbon 14 isotope is used in carbon dating.
2.It can be used to determine the age of non-living things like rocks.
Which of the statements given above is/are incorrect?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: B
Notes:

Explanation: Carbon dating – Living things have carbon in them in various forms. Plants and animals get their carbon from the atmosphere.

  • When they die, C-14 decays and the ratio of C-12 and C-14 changes.
  • The changing ratio of C-12 to C-14 in the remains of a plant or animal after it dies is measured to deduce its approximate age.
  • Exceptions to carbon dating – It cannot be used to determine the age of non-living things like rocks, for example.
