Changes in the Earth’s Crust Model

Model Size:34*34*21cm

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.

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: 43*24*15cm The product demonstration water is widely distributed on the land surface. During the flow process, it constantly changes the surface morphology and shapes into various types of flowing water and landforms. The flow of water is most active in wet areas.
