Answer 2

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

Step-by-step 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.
