The higher the uranium-to-lead ratio of a rock, the more the Pb-206/Pb-204 and Pb-207/Pb-204 values will change with time.

If the source of the solar system was also uniformly distributed with respect to uranium isotope ratios, then the data points will always fall on a single line.

Helium is not light enough to escape the Earth's gravity (unlike hydrogen), and it will therefore accumulate over time.

The current level of helium in the atmosphere would accumulate in less than two hundred thousand years, therefore the Earth is young.

While these values do not compute an age for the Earth, they do establish a lower limit (the Earth must be at least as old as any formation on it).
