Potassium argon dating and carbon 14 dating
Radioactive decay allows geologists and physicists to measure the age of ancient fossils, rocks and even the Earth.
This process is called radiometric or radioactive dating.
Standing roughly in the centre of New Zealand’s North Island, Mt Ngauruhoe is New Zealand’s newest volcano and one of the most active (Figures 1 and 2).
It is not as well publicized as its larger close neighbour MT Ruapehu, which has erupted briefly several times in the last five years.
Two situations where we can do this involve Potassium-40 atoms and Carbon-14 atoms.
All radioactive atoms decay to become a more stable kind of atom.
NUPEX aims to provide teachers and students with reliable, up-to-date information on nuclear science in several major European languages.
The information on this site is interesting and easy to understand, with helpful visual aids and explanations at every step of the way.
Explosions of ash completed this long eruptive period.
This essay shall focus on the importance of radio carbon dating, potassium argon dating, seriation and stratigraphy to the archaeological study.
Accurate dating has always been of importance to scientist and archaeologist alike.
Radiometric dating is possible because the radioactive decay of large numbers of radioactive atoms follows a predictable pattern.
This predictability allows scientists to measure the age of an object if they can work out how many radioactive atoms were originally present.
Plus, the site is extremely easy to use, to encourage pupils to explore the information here on their own.
