Question

Which of the following is the relatively most accurate method for dating fossils?
  1. Potassium - argon method
  2. Uranium - lead method
  3. Electron spin resonance method
  4. Radio carbon method


Solution

The correct option is C Electron spin resonance method
Electron spin resonance method is relatively most accurate method for dating fossils.

Electron spin resonance dating is a technique that can directly detect unpaired or odd electrons in atomic or molecular systems. In this technique, a static magnetic field and microwaves are used to observe the behavior of the unpaired electrons in the material being studied. The study of the behavior of the electrons in a sample gives information about the condition of the sample.
