Potassium carbon dating tagalog meaning
For example, there is a radioactive form of potassium (potassium-40) that decays into argon (argon-40).The unstable potassium isotope is called the parent while the argon product is called the daughter. Doesn’t that prove the world is millions of years old?Radioactive dating may be one of the big questions looming in your mind.It came from a geologic philosophy, not a scientific measurement.Note too that radioactive dating is something that most people don’t understand.Normal people are not familiar with isotopes, mass spectrographs, rubidium, strontium or half lives.We find ourselves in the position where we are being asked to trust the specialists, of not being able to check the facts first hand.
How can we know what disturbances have affected the elements in our rocks? Did you hear about the old wood cutter who was bragging about his axe?
We don’t know what happened to the rock during its ‘lifetime’.
An hour glass is only useful if it is not disturbed.
Some isotopes, however, are unstable and decay radioactively into other elements.
There are many different radioactive isotopes that are used for radiometric dating.
