Model Size: 45*19.5*25cm Set of 2 This product is suitable for use in teaching geological structures during geography teaching in secondary schools. The model visually shows that the rock layer is bent by the force to form a fold, or the fault is formed by the uneven force. The formation of wrinkles and faults changed the surface morphology. The model can also enhance students' perceptual knowledge, solve the strong ablation effect of the free external force that students can hardly grasp, make the anticline become a valley, or incline into a mountain, and can determine the anticline and the oblique from the old and new relationship of the rock formation in the model.
