The correct statement is:
**All non-living things contain uranium-238 and the amount begins to decrease when the rock comes to the surface.**
Uranium-238 is used in radiometric dating to determine the age of rocks because it decays at a known rate (its half-life), and thus the ratio of uranium-238 to its decay products can indicate how long it has been since the rock last underwent certain geological processes.
