Question

The law of superposition uses relative age to determine the age of rocks and fossils. What is absolute age?

Answer 1

Absolute age refers to the specific age, usually measured in years, of a rock, fossil, or other geological material. It provides an exact or precise age, often determined through radiometric dating methods, such as measuring the decay of radioactive isotopes within the material. Absolute age provides a more accurate and objective measurement compared to relative age, which only establishes the order of events or materials in relation to each other.
