Three-dimensional representations of a landscape are ideal teaching materials for geographic education. They are both easier to understand than maps and enable students to comprehend the concept of contour lines in topographic maps. The training of geological understanding can be elevated by using type reliefs showing geomorphologic typical sites like a glacier with its moraines, a fjord or a volcanic island, etc. But a terrain model can also simply familiarise the pupils with the surroundings of their place of living and the morphology of their country respectively.
It is also possible to build a terrain model with pupils. A lot of easy techniques to create models exist .
 See for example Zurflüh, Hans. Das Relief. 1950.
