History of Events – Relative Age
![Page 3: History of Events – Relative Age 1.Original horizontality Layers are deposited horizontally. 2.Superposition Younger layers are on top of older ones](https://reader036.vdocuments.us/reader036/viewer/2022062517/56649f065503460f94c1b3b5/html5/thumbnails/3.jpg)
Principles
1.Original horizontalityLayers are deposited horizontally.
2. SuperpositionYounger layers are on top of
older ones.3. Cross-cutting relationships
Faults and intrusions are younger than the layers they cut across.
