The concept of latitude is used frequently in the geography and the astronomy. For the first science, allows you to identify the distance that separates a point from the surface of the Land of the Ecuador, calculated and expressed in sexagesimal degrees meridian.

It can be said that, in this sense, latitude is the path angular that separates the Equator from any land point. This measurement is carried out taking into account the meridian to which the angular point corresponds. It should be remembered that the meridians are the great circles of the Earth’s sphere that pass through the poles, individualized as imaginary lines that allow you to set the schedule.

According to him hemisphere in question, it is possible to speak of North latitude or South latitude. To indicate which hemisphere the coordinate corresponds to, the latitude can include a lettered specification (“N” or “S”, by North or South) or with signs (“+” in the case of North and “-“, for him South).

If someone wants to express that a point is 28 degrees North latitude, for example, it will indicate the following: 28ºN or + 28º. On the other hand, if the intention is to indicate something that is at 12 degrees South latitude, the correct way to express it will be 12ºS or -12º.

In our planet, the climate of a particular region is partly linked at your latitude. For example, cities very close to the equator have the highest temperatures and, conversely, the further away they are from that latitude, the colder the climate, as is the case with the poles, which are the most distant points from the equator. For a more detailed study of climatic issues and the characteristics of each region, a division has been established into three broad latitudinal zones, which are the following:

* the intertropical: which is also known as hot, tropical, or steamy, and is in the middle of the Tropics of Cancer and Capricorn. There the rays of the Sun They impact perpendicularly throughout the year, which is why their temperatures are very high and are very conducive to the formation of jungles, deserts and savannas. A clear example of a country located in this area is Colombia;

* the temperate: in this case, we can establish a subdivision, taking into account the North zone on the one hand and the South zone on the other; Both are located between the polar circles and the tropics, but the first is between the Arctic circle and the Tropic of Cancer and the second, between the Antarctic circle and the Tropic of Capricorn. In these regions, where it is common to find a desert, a meadow or a forest, the sun’s rays are projected with a certain inclination, which has repercussions in a more temperate and moderate climate, which allows differentiating the seasons of the year more clearly than in the previous case;

* the polar: here it is also possible to distinguish between the North polar zone, located at the same Arctic pole, and that of the South, at the Antarctic pole. In these regions, the sun does not affect with intensity at any time of the year, which explains that its temperature never be warm.

Within the astronomical field, on the other hand, the concept of latitude consists of the distance that is recognized starting from the Ecliptic to any point located in the celestial sphere towards a pole. This distance is indicated in degrees.

Other uses of the term refer to the extension of a province, locality, district or a kingdom, and to the smallest dimension of the 2 that are observed in figures with flat faces.
