← ScienceWhich outcome accelerates uranium ore's isotopic change in a geological formation?
A)Elevated groundwater oxygen concentration✓
B)Increased overburden pressure stability
C)Decreased ambient radiation shielding
D)Reduced geothermal gradient variance
💡 Explanation
An increased groundwater oxygen concentration accelerates isotopic change of uranium ore accelerating radioactive decay because it enhances oxidative weathering, causing preferential leaching of certain isotopes; therefore increasing change, rather than being stable because of pressure or decreased radiation.
