What Are The Main Parallels Of Latitude

The Earth's circles of latitude are the circles formed by the intersection of the terrestrial sphere with an imaginary plane perpendicular to axis of the Earth's rotation. These parallel parts, together with the meridians, the so-called geographical coordinates, form a reference system that, among other things, allows us to find an exact or particular location on the globe based on the latitude and longitude. These geographic coordinates have been used during the history of humanity as important aspects for navigation such as GPS coordinates. If you are not very clear on what are the main parallels of latitude, today we're going to try to explain some of them.

We can say that there are five major parallels of latitude. The first is the Arctic Circle (Latitude 66 ° 33 'N = 90 - 23 ° 27'). The Arctic Circle demarcates the southern end of the polar summer solstice and the winter solstice night. Moreover, it is interesting that on the day of the summer solstice, the sun does not set for 24 hours, while during the winter solstice, the sun does not rise for 24 hours.

The parallel known as the Tropic of Cancer is in the tropical northern hemisphere. It is the parallel that is situated to the north of Ecuador, at an exact of latitude 23 ° 26' 16''. At this point, it is important to note that this parallel moves towards the southern half for a second per year. It is equally interesting that this parallel delimits the northernmost point where the sun shines from the zenith, which occurs during the June solstice.

The Equator is the parallel that divides the surface of the Earth into two parts, known as the northern hemisphere and the southern hemisphere. Therefore, its latitude is exactly 0 °. The sun culminates in the zenith at the Spring equinox and the Autumn equinox.

The Tropic of Capricorn is the parallel at the latitude of 23º 26 '16. What lies further south and what is defined is the southernmost point where the sun can occupy the zenith at noon.

Finally we have the Antarctic Circle, the parallel of a latitude of 57 ° 90 '3 - located in the southern part of the equator. In the entire area south of the Antarctic Circle there is at least one day in which the sun is visible for 24 hours. Furthermore, there is also a day when the sun is not visible for 24 hours.
