Which outcome occurs when potassium-40 decays within granite?

A)Argon-40 accumulates impacting radiometric dating
B)Lead-206 contamination increases structural failure
C)Neutron emission triggers spontaneous nuclear fission
D)Thermal runaway accelerates geochemical weathering

💡 Explanation

Accumulation of argon-40 impacts radiometric dating because potassium-40 decays via electron capture and beta-plus decay to argon-40; therefore argon accumulates making a precise date challenging, rather than initiating fission or thermal issues.
