A globe is a three-dimensional scale model of a spheroid celestial body such as a planet, star or moon, in particular Earth, or, alternatively, a spherical representation of the sky with the stars (not the Sun, Moon, or planets, because their positions vary relative to those of the stars; however, the "orbit" of the Sun is indicated).Globes are the only geographical representation of Earth that has no distortion. Spheres such as the Earth are mapped onto a flat surface using a map projection with an inherent degree of distortion. These projections can either enforce angle preservation or area preservation. A typical scale for a globe is ca. 1:40 million.
The Earth is obviously the most popular planet represented but globes of the Sun, the Moon and other celestial objects have been made, including fictional ones.
The earliest globe, called the "Nürnberg Terrestrial Globe", was made during the years 1490-1492 by German mapmaker Martin Behaim.
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 dayA day is any of several different units of time. The word refers either to the period of light when the Sun is above the local horizon or to the full day covering a dark and a light period. Introduction Different definitions of the day are based on the aps and seasonThis article is about divisions of a year. For other uses of the term, see season (disambiguation). Fig. 1 This is a diagram of the seasons. Note that, regardless of the time of day (i. the Earth's rotation on its axis), the North Pole will be dark, and ts change.
Sometimes a globe has relief, showing topographyTopography a geography term, refers to the "lay of the land", or the physiogeographic characteristics of land in terms of elevation, slope, and orientation. Terrain is a similar term, used more to describe the land itself than the study of it. Topographic; in the case of a globe of the Earth the elevations are exaggerated, otherwise they would be hardly visible.
CartographyCartography (or mapmaking is the study and practice of making maps or globes. Maps have traditionally been made using pen and paper, but the advent and spread of computers has revolutionized cartography. Most commercial quality maps are now made with map
