What Are the Bumps on Some Globes?
A bumpy globe is simply showing the relief of the earth's surface. These bumps and dips are measured relative to seal level.
Why Do Some have a Metal Ring?
The metal ring seen around many globes is called a meridian. Before the introduction of latitude and longitude lines, this was used to help identify positions on the globe. Now it is used primarily for aesthetics and helps in stabilization.
Why Do Some Look Tilted?
The tilt seen on some globes is reflective of the 23.5 degree tilt of the earth. We have the change of seasons because of this tilt. This tilt is there to provide a more accurate model of the earth.
Spinning globes are a wonderful addition to the home, office or classroom environment. They're sure to bring hours of learning enjoyment.
