why is radioactive dating important when approximating the age of earth?\no scientists can identify different life forms using index fossil records.\no scientists can examine how temperature changes within earth’s interior.\no scientists can determine the order of when rocks formed on earth.\no scientists can analyze changes in chemical concentration of atmospheric gases.
Answer
Brief Explanations:
Radioactive dating is used to find the age of rocks. By determining the age of rocks, scientists can figure out the order in which rocks formed on Earth, which helps in approximating the age of the Earth. The other options are about different geological or paleontological - related studies not directly related to radioactive - dating for Earth - age approximation.
Answer:
Scientists can determine the order of when rocks formed on Earth.
