Scientists can determine the order of when rocks formed on Earth.
More precisely: radiometric (radioactive) dating measures the decay of unstable isotopes (e.g., uranium → lead) with known half‑lives to calculate absolute ages for rocks and minerals. That lets geologists date rock formation (and thus major events) rather than just place them in relative order. Combining radiometric ages from Earth rocks and meteorites gives the ~4.54 billion‑year age for Earth.
