It travels a short distance before encountering an electron in the material, where it annihilates to two gamma rays (photons) of .511 MeV each.. 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..
