Its crust is continually being created, modified, and destroyed.All rocks and minerals contain tiny amounts of these radioactive elements.Radioactive elements are unstable; they breakdown spontaneously into more stable atoms over time, a process known as radioactive decay.Here you can discover the power of geological processes.Knowing this first: that scoffers will come in the last days, walking according to their own lusts, and saying, “Where is the promise of His coming?

Since the 1950s, geologists have used radioactive elements as natural "clocks" for determining numerical ages of certain types of rocks. "Forms" means the moment an igneous rock solidifies from magma, a sedimentary rock layer is deposited, or a rock heated by metamorphism cools off.

As discussed before, the assumptions influence the interpretation of the data.

There are three main assumptions that must be made to accept radiometric dating methods.

Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.
