Answer:

he age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectromer

Explanation:

Radiometric dating is used to establish the age of rocks by examining the ratio of two distinct isotopes in a sample. Due to the expected decay of radioactive isotopes, geologists can establish the age of a sample using technology such as the thermal ionization mass spectrometer.
