why is radioactive dating important when approximating the age of earth? scientists can identify different life forms using index fossil records. scientists can examine how temperature changes within earth’s interior. scientists can determine the order of when rocks formed on earth. scientists can analyze changes in chemical concentration of atmospheric gases.
Answer
Brief Explanations:
Radioactive dating is used to determine the age of rocks. By knowing the age of rocks, scientists can figure out the order in which rocks formed on Earth, which helps in approximating Earth's age. Identifying life - forms with index fossils, examining Earth's interior temperature changes, and analyzing atmospheric gas chemical concentrations are not the main purposes of radioactive dating for Earth - age approximation.
Answer:
Scientists can determine the order of when rocks formed on Earth.
