How does carbon dating determine the age of an object

More information
Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over naturally-occurring isotopes are known. Some do not change with time and form stable isotopes i. The unstable or more commonly known radioactive isotopes break down by radioactive decay into other isotopes.

Is carbon dating a reliable method for determining the age of things? |

Newgrange is one of the best examples in Ireland and in Western Europe, of a type of monument known to archaeologists as a passage-grave or passage-tomb. It was constructed around BC, according to the most reliable Carbon 14 dates available from archaeology. This makes it more than years older than the Giza Pyramids in Egypt, and 1, years more ancient than Stonehenge. Newgrange was built in a time when there was only stone, not metal, used as an everyday material for tools and weapons.

How do scientists figure out how old things are?

Following the somewhat serendipitous discovery of radioactivity by Becquerel, many prominent scientists began to investigate this new, intriguing phenomenon. During the beginning of the twentieth century, many radioactive substances were discovered, the properties of radiation were investigated and quantified, and a solid understanding of radiation and nuclear decay was developed. The spontaneous change of an unstable nuclide into another is radioactive decay. The unstable nuclide is called the parent nuclide ; the nuclide that results from the decay is known as the daughter nuclide. The daughter nuclide may be stable, or it may decay itself.

The Minoan eruption was a major catastrophic volcanic eruption that devastated the Aegean island of Thera now called Santorini in around BCE. Although there are no clear ancient records of the eruption, its plume may have been described in the Egyptian Tempest Stele , [8] and the ensuing volcanic winter coincides with a cold wave mentioned in the Chinese Bamboo Annals. Geological evidence shows the Thera volcano erupted numerous times over several hundred thousand years before the Minoan eruption. In a repeating process, the volcano would violently erupt, then eventually collapse into a roughly circular seawater-filled caldera , with numerous small islands forming the circle. The caldera would slowly refill with magma, building a new volcano, which erupted and then collapsed in an ongoing cyclical process.
