Radiocarbon dating for kids
While on a hike, a couple from Germany found what is now referred to as the Iceman.
But even radiometric dating does not actually directly measure the age of something (there is no substance called “age”).
However, even if we measured how much of A and B were in a sample of rock, could we figure out how long A has been changing into B, and therefore how old the rock is? We don’t know what the rock was like when it formed, or what has happened to it since. All of these factors will affect how “old” the rock appears—in practice, usually making it appear a lot older than it really is.
