Question

Which of the following is relatively more accurate method of determining the age of fossils?

• A. Uranium-lead method
• B. Radio-carbon method
• C. Study of carbohydrates/ proteins in rocks
• D. Electron-spin resonance method

Answer 1

The correct option is A Uranium-lead method

• The dating of fossils using uranium and lead is one of the oldest processes of doing so.
• This is also the most redefined methods of fossil-dating.
• This process can enable dating of fossils that are around 1 million years to over 4.5 billion years old.
• This process has a routine precision in the 0.1–1 per cent range and hence, can be considered the most accurate method of fossil-dating.
  
• So, the correct answer is 'Uranium-lead method'.
