Final answer:

The constant half-life of uranium-238 allows accurate dating of rocks by measuring its decay rate.


Explanation:

The characteristic of the radioactive isotope uranium-238 that makes it useful for accurately dating the age of a rock is the isotope's constant half-life.

Uranium-238 has a half-life of 4.5 × 10^9 years, which means it decays at a consistent rate over time, allowing scientists to determine the age of rocks by measuring the ratio of uranium-238 to its daughter isotopes.

By analyzing this radioactive decay process, researchers can determine the age of rocks and even estimate the age of the Earth itself.
