← ScienceWhich outcome results when measuring potassium-40 abundance in rock?
A)Date of rock formation decreases
B)Argon-40 concentration remains unchanged
C)Radiometric dating becomes more inaccurate
D)Mineral's crystallization event may be dated✓
💡 Explanation
Using Potassium-Argon dating relies on radioactive decay. Potassium-40 decays to Argon-40. Accumulation of Argon allows dating samples because measurement facilitates age estimation based on half-life calculations; rather than, altering concentrations themselves under normal terrestrial conditions.
