This model makes it possible to reconstitute the original conformation of the continents by the analogy of their contours - The continents can be moved by the user then stabilized by magnetization in the various stages of the evolution - A numbering of the elements facilitates their arrangement (according to a plan provided in the note) - This model makes it possible to explain the expansion of the oceans and the formation of the mountain chains (Himalayas...).
Composition :
- A blue metallic sphere, diameter 250 mm ;
- 15 magnetised elements representing the different continents;
- A support to hold the sphere.
