World is round - A globe is usually mounted at an angle on bearings. In addition to making it easy to use this mounting also represents the angle of the planet in relation to its sun and the spin of the planet. This makes it easy to visualize how days and seasons change. Largest Globes in the world made by man. 1. Eartha, currently the world's largest rotating globe (41 feet in diameter), at the Delorme headquarters in Yarmouth, Maine 2. The Mapparium, 30 foot walk-in globe at the Christian Science complex in Boston, intended to be viewed from within. 3.
