Answer 2

$\huge \boxed{ \underline{ \underline{ \bf{Answer}}}}$

Fossils :

Fossils are the impressions or remains of hard parts of extinct organisms preserved in sedimentary rocks or other media.

Methods to determine the age of fossils :

(i) Relative method :

The fossils which we find in layers closer to the surface of the earth are more recent, the fossils which are found in deeper layers are older.

(ii) Carbon Dating :

Fossils were once living objects and all living objects contains carbon - 14 atoms which are radioactive. When a living organisms dies and forms fossils, it's carbon - 14 radioactive goes on decreasing gradually. The age of the fossils is found by comparing the carbon - 14 radioactive left in the fossil with the carbon - 14 radioactive present in the living object today.

This is how the age is determined.
