Quizplus · Accepted Answer

Radioisotope dating of rocks, combined with fossil analysis, allows geologists to determine relative and absolute ages of rocks and geological events. It is considered the most powerful method for this purpose.

Answer: C
 Geological periods are indeed divided into eras. The current era is the Cenozoic era, which is further divided into the Paleogene, Neogene, and Quaternary periods.

Answer: D

Answer: E
 Radioisotope dating can be performed on any type of rock or material that contains radioactive isotopes, not just fossils.
