Geological Fold and Fault Diagram - Understanding Rock Deformation #3905703 (License: Personal Use)

This black-and-white line diagram depicts a block of stratified sedimentary rock subjected to compressional stress, as indicated by the downward-pointing arrow. The layers are shown tilting and thickening on one side, suggesting either a monocline fold or the early stage of thrust faulting. Such diagrams are commonly used in introductory geology to demonstrate structural deformation mechanisms.

Used in educational web pages, textbooks, or museum exhibits explaining plate tectonics, rock deformation, or structural geology; matches user intent to understand how mountains form or how earthquakes relate to fault systems.
