Globes in Raig

A globe, or sphere, is the three-dimensional scale model or reproduction of Earth. This scale is related to the calculation of the Earth's circumference, which is 40 million meters. Thus most globes have a circumference or perimeter of 1 meter, therefore the scale is 1/40 million, 1cm represents 400km above Earth.

There are two fundamental types of balloons or representations, the political and the physical.

As we introduced before, there are political, physical and other mixed globes that incorporate both characteristics.

A political representation is one where the countries with their borders are reflected. Likewise, the names of these countries and the most significant places, usually their capitals, also appear.

A physical representation is one that shows the most important geographical features. That is to say, Mountains, rivers, lakes, seas, buckets, plateaus, etc. All the place names of the main relief units are indicated, in such a way that a physical as well as topographic globe is often associated. In some physical representation it has been chosen to give relief to the globe, further deepening the 3D representation.

Mixed-type balloons combine these two models of representation and are the most complete of all of them.

Another feature of globes is that they can be illuminated. This is achieved by an internal light bulb, which lights up when you connect it to the power.

Illuminated balloons allow you to observe the performance at night or with the light in the room turned off. In some cases the political / physical representation is even combined with some astronomical representation of stars or constellations.

The internal bulb can be easily replaced when it burns out.

The globes play a fundamental role in education and specifically in education in geography. With this model, children learn to locate places, countries, mountains, etc ... on the surface of the earth, they are curious to find the place where they live and to know much more distant places.

In times where geography has lost a lot of weight in school education, globes are a tool to claim and solve this possible lack of emphasis on this fundamental issue. There are models specifically designed for children, at different ages

Indeed, there are also models of star, lunar and planetary globes. Following the same procedure as in the globes, the celestial planisphere, the surface of the moon or some planets like Mars have also been represented in the form of a globe.

As was the case with the terrestrial globes, lighting has also been added, and all the topographical indications of the different stars.
