Question

You suspect that a sample of rock dates from about 200,000 years ago. If you want to determine an absolute date for this rock, which dating method would you use? A. Principle of inclusionsB. Uranium/lead datingC. Potassium/argon datingD. Carbon/nitrogen dating

Answer 1

Answer:

D. Carbon/nitrogen dating

Explanation:

• The geologist uses a variety of the methods to date the ricks and these forms the radiometric dating, and the tree rings, and ice cores. And the radiometric technique is one of the most useful methods to date the rocks in terms of establishing their ages and by the use of the carbon C-14, isotope.

• Some conditions for the dating include the variations in C ratio in the air, isotopic fractionation, and their contamination. As the carbon has an average; the life of about the  40 years, and is 14 is produced in the upper layers of air and the stratosphere by the interaction of the thermal neutrons and the nitrogen atoms.
