different methods of radiometric dating can be used to estimate the age of a variety of natural and even manmade materials.
radioactive decaythe methods work because radioactive elements are unstable and they are always trying to move to a more stable state. this process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.
Scientists use two kinds of dating techniques to work out the age of rocks and fossils. Absolute dating is used to determine a precise age of a rock or fossil through. Determining the relative age of a rock layer is based on the assumption that.
dating methods to determine the ages of the surrounding rocks.
Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.
