How do you tell if a rock is older?
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
Are there ancient stones in Scotland?

How old do rocks live up to?
Rocks at the surface of the earth are of many different ages. They range from over three billion years old to less than one million years old. We know that one of the laws of physics is that under ordinary circumstances matter can neither be created or destroyed.
Are older rocks on top or bottom?
Over time, the sediments pile up to form horizontal layers of sedimentary rocks. The bottom layer of rock forms first, which means it is oldest. Each layer above that is younger, and the top layer is youngest of all.
How do you tell rocks from youngest to oldest?
Superposition. Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.
