24pcs Sedimentary Rocks

Model Size: 44*24*12cm Through the model, the fold structure phenomenon distributed over a wide range of space and the dynamic change process of its surface morphology can be narrowed down and concentrated, and the students can establish concepts and concepts in this aspect.

Model Size: 44*24*12cm This product is mainly used in the teaching of secondary school geography to teach the seabed topography, the inner circle of the earth, the crustal structure, the topographical changes, the tectonics theory, the formation and distribution of volcanic earthquakes, and the formation of the earth's surface sea and land corridor. These contents are interrelated and cause and effect. For middle school students, it is often difficult to analyze and understand this, and because of its large spatial span and long change time, which is impossible to conduct actual observations, abstract and difficult to understand.

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.

Model Size: 45*21*13cm This product is mainly used in the teaching of geography teaching in middle school to teach the change of terrain and geological structure; the phenomenon of fold structure and its topography is far from the actual life of students, and it is difficult to conduct actual observation because of its large spatial span and long change time. The students are difficult to understand.
