Why is radioactive dating important when approximating the age of Earth?
A.Scientists can identify different life forms using index fossil records.
B.Scientists can examine how temperature changes within Earth’s interior.
C.Scientists can determine the order of when rocks formed on Earth.
D.Scientists can analyze changes in chemical concentration of atmospheric gases.
Answers
Explanation:
The correct answer is A. Scientists can identify different life forms using index fossil records. Geologists and scientists follow a set of principles that are used to understand the different rock forms. There are sedimentary rocks and volcanic rocks that are generally exposed to Earth’s surface. Scietists identify those rocks through this method. In Radioactive dating, the materials are inspected to understand their date, that is to say when they were formed.
