प्रश्न
Describe in brief two methods of determining the age of fossils.
उत्तर
The age of fossils can be determined by the following ways:-
- Radiometric dating: In this method, the age of fossils can be determined by tracing the radioactive elements present in the rocks and by examining them chemically.
- Relative dating: Fossils are found in sedimentary rocks in the form of layers accumulated over a large span of time. Considering the fact that fossils found in the bottom layers are older than those found in the layers above them, geologists find the age of the fossils.
