the radioactive decay of uranium to lead
Answered by GPT 3.5
Yes, I am certain that the radioactive decay of uranium to lead is the answer. This decay process is used in radiometric dating to determine the age of rocks and minerals on Earth. Uranium-lead dating is one of the most reliable methods for determining the age of the Earth, with an estimated age of 4.3 billion years.
