When sedimentary rock is deposited in layers it is deposited horizontally.. Scientists use this “Principle of Original Horizontality” to help them determine the age of the layers.. The older layers of rock are found below the younger layers of rock.. Unscramble the following keywords for today’s lesson:. . Yecad. Iriaovadect. Ootspei. Nsteruon. nadgit. Isotopes . When the nucleus of an atom possesses either too many or too few neutrons compared to the number of protons it becomes unstable. These are called radioactive isotopes. Unstable nuclei split up in a process called radioactive decay and emit radioactive radiation.. Regulation. By. S.M. . Oyeyemi. , T .C. . Akpa. , T.A. . Faru. Nigerian Nuclear Regulatory Authority.
