Choose from a variety of formats depicting the Earth in a detailed, three-dimensional display. Inflatable, writable globes can be used for a hands-on lesson in world geography, with the inflated globe capable of being tossed around the room and information being recorded directly on the globe through use of wet-erase markers. Mounted relief globes show mountains jutting out from the ocean-level surface of the globe, and other models include demonstrations of seasons on Earth or representations of the moon and other celestial bodies.
