To figure out the age of the earth, it is important to know how old the rocks on it are. Scientists can date rocks by measuring the amount it of radioactivity, or rays of energy, they give off. All rocks contain some uranium, which causes radioactivity, and that uranium give off invisible rays of energy which slowly change the u
