The Fold and Fault Model is a five-piece geology teaching aid that illustrates the major folds and faults found in Earth's crust. It provides a visual representation of fold planes, the effects of tectonic stress, and the structural elements of geological faults. The model is crafted by subject matter experts and includes an identification key for easy recognition of features. It is a practical tool for earth science instruction, helping students understand tectonic processes, crustal deformation, and structural geology concepts.
