Relative dating provides an order of events, not an exact numerical age. It tells you which rock layer or fossil is older or younger than another, but not how old it is in years.

Here's a breakdown of what relative dating offers:

* Sequence: It establishes the sequence in which rocks and fossils were formed.

* Comparison: It compares rock layers and fossils based on their positions and characteristics.

* Timeframe: It places events within a broad timeframe, indicating whether they occurred earlier or later than others.

Think of it like this: Imagine you have a stack of books. You can tell which book is on top and which is on the bottom, but you don't know how long those books have been there. That's what relative dating does for rocks and fossils.

Here are some key principles of relative dating:

* Superposition: Younger rock layers are usually found on top of older ones.

* Cross-cutting relationships: If one rock layer cuts through another, the cutting layer is younger.

* Fossil succession: Certain fossils are found only within specific rock layers, helping to establish their relative ages.

In contrast, absolute dating provides an estimated numerical age in years using methods like radiometric dating.
