Limitations of radiometric dating

Lord Kelvin and Clarence King calculated the length of time required for the Earth to cool from a white-hot liquid state; they eventually settled on 24 million years.

he question of the ages of the Earth and its rock formations and features has fascinated philosophers, theologians, and scientists for centuries, primarily because the answers put our lives in temporal perspective.

Until the 18th century, this question was principally in the hands of theologians, who based their calculations on biblical chronology.

Based on evidence from radiometric dating, the age of the Earth has been estimated to be approximately 4.5 billion years.

Radiometric dating is largely done on rock that has formed from solidified lava.

Lava (properly called magma before it erupts) fills large underground chambers called magma chambers.
