Do rocks last forever?

Rocks do not last forever. Most wear away with time and turn to sand and dust, sometimes the sand and dust gets cemented together to make different rocks, but they too will erode away. Some rocks will be carried back into the earth to melt, perhaps to be recycled into volcanic rocks.

How old is the average stone?

On average, the rocks you will find walking around are probably less than a billion year old. Around 500 million, but higher or lower depending on whether you’re hiking at the top of the himalayas (younger) or the bottom of the grand canyon(older) or on the beach (could be either), and what you’re picking up.

How can you tell the age of a rock?

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.
