← ScienceWhich consequence primarily results when a Potassium-40 nuclide within igneous rock undergoes beta decay?
A)Formation of Argon-40 increases✓
B)Radiative heat flux decreases
C)Material density uniformly decreases
D)Seismic wave velocity decreases
💡 Explanation
Argon-40 is formed because Potassium-40 undergoes beta decay transforming a neutron into a proton via electron emission through nuclide transmutation. Therefore Argon-40 abundance increases, rather than heat fluctuating, and density or wave parameters changing since that involves mechanical changes.
