* Angular Unconformity: This type of unconformity occurs when:
* Older, horizontal layers of rock are tilted or folded (due to tectonic activity).
* These tilted/folded layers are then eroded.
* New sediments are deposited on top of the eroded surface, creating horizontal layers that sit at an angle to the older, tilted layers.
The difference in angle between the older and newer layers is what gives this unconformity its name. It represents a significant gap in geologic time, where erosion and uplift occurred before deposition resumed.
