Question

Quizplus · Accepted Answer

The K/Ar (Potassium-Argon) dating method is most appropriate for dating volcanic rock because it relies on measuring the decay of radioactive potassium (40K) to argon (40Ar), a process that occurs at a known rate. This method is particularly useful for dating volcanic rocks and ash layers, which contain potassium but can't be used directly on fossils, charcoal, pottery, or other organic materials.
