Assignment Help:

Does radioactive dating with isotopes of uranium and thorium provide an estimate of the starting, middle, or end of the period of Earth's formation? Explain your answer

No, this method estimates the age of the oldest un-melted surface rocks on Earth. As the surface of Earth probably melted many times as the planet was produced, the Earth should be older than these rocks.
