But all that was trumped within the late 1800s and early 1900s by the invention of radioactivity, which was quickly adopted by calculation of the charges at which various radioactive substances decay [supply: Badash]. Earth scientists have used that data to find out the age of Earth’s rocks, in addition to samples from meteorites and rocks brought back from the moon by astronauts. For example, they’ve seemed at the state of decay of lead isotopes from rocks, after which in contrast that to a scale based on calculations of how lead isotopes would change over time. From that, they’ve been ready to determine that Earth formed roughly 4.Fifty four billion years in the past with an uncertainty of lower than 1 percent [source: U.S. Geological Survey].
