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 the chemical concentration of atmospheric gases.

Scientists can determine the order of when rocks formed on Earth.

Explanation:

Radioactive dating is the technique in which scientists used radioactive material like carbon or uranium to date the materials. This method of dating is based on the known decay rate of the isotopes of an element. Uranium, Carbon, and potassium are few examples of elements commonly used in radioactive dating.
