The correct answer is layers of rock.

The age of earth is determined by the layers of rock. By chemical nature rock minerals contain certain radioactive isotopes which can be used to determine the age of the earth. By measuring the concentration of stable end product and knowing the concept of initial concentration and half life,  the age of rocks can be determined. This procedure is used to determine the age of earth.The age of oldest terrestrial rock gives the approximate age of earth.

The scientific name of any organism is written by its genus name and species name. This is called binomial system of naming. While writing the scientific name of an organism, the name of the genus written first with a capital letter and the name of the species is written second with a small letter.  When typed scientific name is in italics and when it is hand written the genus name and the species are to be underlined separately.
