PART 1: Back to Basics PART 2: Problems with the Assumptions PART 3: Making Sense of the Patterns This three-part series will help you properly understand radiometric dating, the assumptions that lead to inaccurate dates, and the clues about what really happened in the past.

Most people think that radioactive dating has proven the earth is billions of years old.

Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.

Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.

In fact, you might like this term better, because the dating method relies on the known decay rate of radioactive isotopes.

The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.Part 2 explains how scientists run into problems when they make assumptions about what happened .An hourglass is a helpful analogy to explain how geologists calculate the ages of rocks.Learn about three common types of radioactive decay: alpha decay, beta decay and gamma decay. You simply subtract your birth date from the current date. It was also discovered that these elements decayed into other elements at fixed rates. So we have to rely on something called radiometric dating to figure out the age of rock.
