Carbon-14 Dating Can Be Used to Date

Question

Carbon-14 dating can be used to date
A) old volcanic rocks.
B) old sedimentary rocks.
C) young organic material.
D) young apatite crystals.

Accepted Answer

Carbon-14 dating can only be used to date organic material that is younger than 50,000 years old. It is not effective for dating rocks, whether they are volcanic or sedimentary, as they do not contain organic matter. Apatite crystals may contain trace amounts of carbon, but they are generally not considered organic material and are not suitable for carbon-14 dating.
