What are the bumps on some globes and why aren they on all globes?
The bumps are called raised relief and better emphasize the mountainous areas of the world. They are there so that you can SEE & FEEL the mountains although their actual height on the globe does not have any relationship to the true relative heights of the mountain ranges. Raised relief is found on 9″, 12″ and 16″ diameter non-illuminated globes. On a smaller globe it would be difficult to maintain any degree of accuracy. On a very large diameter globe, i.e., 20″ & 32″, the method of manufacturing doesn t lend itself to incorporating this feature.
