The name given to layers of tilted rocks that are overlain by younger, more flat-lying rock layers is an angular unconformity.

Here's why:

* Unconformity: This term refers to a break in the geologic record, indicating a period of erosion or non-deposition.

* Angular: The key characteristic is the angular relationship between the tilted older rocks and the flat-lying younger rocks. This angle indicates a period of uplift, tilting, and erosion before the younger layers were deposited.
