Answers
Answer:
Fossils are traces, remains and impressions of organisms from remote past. They are often referred as "written documents of evolution".
Two methods of determining the age of fossils are:-
1. Relative dating- The organisms found on shallow depths are more recent than those found deeper.
2. Dating using isotopes- This includes carbon dating, uranium and lead dating etc. The age of fossil is calculated by using half life concept.
Hope this helps you.
Answer:
◇FOSSILS⏭ The remnants and impressions of the buried organisms remain underground.These are called as fossils.
Carbon dating technology is used to calculate the time passed since the death of organisms by measuring the radioactivity of C-14 and the ratio of C-14 to C-12 present in their body.
It was discovered by Sir Willard Libby.
