Potassium-argon would be used to date the age of a:
A)sedimentary layer
B)bone breccia

Question

Quizplus · Accepted Answer

Potassium-argon dating is a radiometric dating technique that is used to date volcanic rocks, especially lava flows. Potassium-40 decays to argon-40 with a half-life of 1.25 billion years, which allows for dating of rocks up to millions of years old. Sedimentary layers, bone breccia, and trees are not typically dated using potassium-argon dating.
