How does radioactive decay related to radiometric dating

Some isotopes, however, are unstable and decay radioactively into other elements.

There are many different radioactive isotopes that are used for radiometric dating.

Everything is composed of elements and there are about 90 naturally occurring ones, such as hydrogen, carbon, oxygen and iron.

Each element comes in different forms, called isotopes, most of which are stable and do not change.

We don’t know what happened to the rock during its ‘lifetime’.

An hour glass is only useful if it is not disturbed.

‘It’s only had two new heads and three new handles.’ The question is: how old was his axe? When a geologist hammers off a sample of rock he needs to know its history.It came from a geologic philosophy, not a scientific measurement.Note too that radioactive dating is something that most people don’t understand.But after rocks crystallize from molten magma, they can be heated and cooled; they can be affected by metamorphic events and groundwater.These geologic events can cause elements to be gained and lost to the rock.
