which stable element is used to determine the age of volcanic rock?\nargon\ncarbon - 14\npotassium\ncarbon - 12
Answer
Brief Explanations:
- Carbon - 14 is used for dating organic materials, not volcanic rocks.
- Carbon - 12 is a stable isotope but not used for rock dating.
- Potassium is not the stable element used for volcanic rock dating.
- Argon is used in the argon - argon dating method for volcanic rocks. When volcanic rocks form, argon can be trapped. By measuring the ratio of argon isotopes, the age of the rock can be determined.
Answer:
argon
