Compressional Tectonics: How Rock Layers Deform Under Pressure #3762347 (License: Personal Use)

This diagram illustrates compressional tectonic forces acting horizontally on stratified rock layers, causing them to buckle, fold, and fracture along a thrust fault. The red arrows indicate opposing directional pressure, while the displaced upper block (hanging wall) moves up and over the lower block (footwall), characteristic of convergent plate boundaries. Such deformation is common in mountain-building regions like the Alps or Himalayas.

Used in geology education, earth science textbooks, and online learning modules to explain structural geology concepts; matches user intent for understanding fault mechanics and mountain formation.
