Question

With the help of carbon dating technique which one of the following can be measured
A. Age of fossil
B. Age of rock
C. Age of monument
D. Age of universe

Answer 1

Hint: This is also known as radiocarbon dating. It involves the use of a radioactive isotope of carbon formed when the carbon interacts with the oxygen. It has its uses in different fields of study.

Complete answer:
Carbon dating is a method used to calculate the age of any material i.e. organic with the help of radioactive carbon isotope. This is also known as radiocarbon dating. This method was developed at the University of Chicago in 1940 by Willard Libby.
Carbon is constantly produced in the environment by interaction with the cosmic rays. This when reacts with the oxygen in the air, it makes it radioactive which is consumed by the plants in the process of photosynthesis. When the plant dies this exchange stops and the radioactive carbon remains in the plants. This concentration starts to decrease due to decay. This calculation of the carbon helps to know the age of the plant.
This process became popular in the field of archeology. This has allowed the research to extend back in date till the ice age, bronze age etc.
This can be used to study the fossils of animals and other species found in the earth to know their age.

So the correct answer is A i.e age of fossils.

Note: This method was developed in University of Chicago in 1940 by Willard Libby. He was also awarded a Nobel Prize in 1960 in chemistry. This process became popular in the field of archeology. This has allowed the research to extend back in date till the ice age, bronze age etc.
