Question

The best way of direct dating of fossils of recent origin is.....
a) radio-carbon method
b) uranium-lead method
c) potassium-argon method
d) both a and c​

Answer 1

Answer:

The correct option is d) both a and c

Explanation:

• Fossils are dated in order to determine what the age of a particular fossil understudy might be.

• Radio-carbon dating is one of the most common methods for the determination of the time of a fossil formation. This is because the body of every organism contains carbon. The radioactive form of carbon is C-14. Scientists calculate the half-life of C-14 to determine the fossil age.

• Potassium-argon method is also used for the determination of fossil age. Potassium is converted into argon and by determining the half-life of the amount of potassium converted into argon we can determine the half-life of a fossil.
