Question

Which of the following are absolute radioactive isotope dating methods? (A) Radiocarbon Dating
(B) Potassium/Argon Dating
(C) Thermoluminescence
(D) Fluorine Dating
Choose the correct answer from the options given below:

• A. (A), (B) and (C) only
• B. (A), (B) and (D) only
• C. (A), (C) and (D) only
• D. (B), (C) and (D) only

Hint:

Absolute dating methods like Radiocarbon Dating, Potassium/Argon Dating, and Thermoluminescence provide precise ages, unlike relative dating methods like Fluorine Dating.

Answer 1

The Correct Option is A

Step 1: Understanding absolute dating methods.
Absolute dating methods are used to determine the exact age of an object or specimen by measuring the amount of radioactive isotopes present. Here are the methods listed:
- Radiocarbon Dating (A): This is an absolute dating method used to date organic materials by measuring the decay of carbon-1(4)
- Potassium/Argon Dating (B): This method is used for dating volcanic rocks and fossils by measuring the ratio of potassium to argon isotopes.
- Thermoluminescence (C): This technique is used to date materials like ceramics and rocks by measuring the light released when the material is heated.
- Fluorine Dating (D): This is a relative dating method used to compare the accumulation of fluorine in bones, but it is not an absolute dating method.
Step 2: Conclusion.
Radiocarbon Dating, Potassium/Argon Dating, and Thermoluminescence are absolute dating methods.
Final Answer: \[ \boxed{\text{The correct answer is (1) (A), (B) and (C) only.}} \]
