The correct response is the radioactive decay of uranium to lead. This method, known as uranium-lead dating, allows scientists to estimate the age of zircon minerals, which can provide insights into the age of the Earth itself, indicating it is at least 4.3 billion years old.
Which allowed scientists to determine that Earth was at least 4.3 billion years old?(1 point) Responses chemical reactivity of zircon ions chemical reactivity of zircon ions the electrical conductivity of uranium ions the electrical conductivity of uranium ions the radioactive decay of uranium to lead the radioactive decay of uranium to lead magnetic field surrounding zircon
