Answer: Putting things in order from youngest to oldest.
Explanation:
Relative dating entails the placing of events in a sequence of their occurrence based on relationships between earth materials. In order to date a rock using the techniques of relative dating, some principles are usually followed. Some of the principles of relative dating are:
Principle of superposition
Principle of original horizontality
Principle of lateral continuity
Cross-cutting principle
Principle of fossil and fauna succession.
All of these principles helps establish succinct relationships between rock layers and what they contain. Fossils which are the preserved remains of organisms in rocks are very essential in relative dating of rocks.
Putting things in order from the youngest to the oldest is relative dating. Other options are categorized as absolute dating. In absolute dating, an exact date is affixed to a geologic event.
