The north pole is in the northern hemisphere.
The etymology of boreal takes us to Latin, more precisely to the word boreālis . It is an adjective that can be used to refer to what is linked to the north or the Boreas .
The cardinal point that is located in front of the observer to whose right is east is called north . The Boreas , meanwhile, is a wind that comes from the north.
The northern hemisphere
Planet Earth can be symbolically divided into two halves called hemispheres . Each hemisphere is the result of the division of the terrestrial sphere by the equator : the great circle that is equidistant from the poles.
That hemisphere where the boreal pole is located is called the boreal hemisphere . It should be noted that the boreal pole is one of the points at which the axis of rotation cuts the Earth's sphere; specifically, the pole that is located in the north. Since boreal and north are synonyms, one can also speak of the northern hemisphere and the north pole .
The northern hemisphere and the southern hemisphere are therefore separated by the equator. Most of the emerged lands are found in the northern hemisphere, which contains all of Europe , Central America and North America ; large parts of Asia and Africa ; a small sector of South America ; and several islands in Oceania .
It is estimated that almost 90% of the world's population lives in the northern hemisphere. In this hemisphere, winter usually begins on December 21 and summer on June 21 , the opposite of what happens in the southern hemisphere.
An atmospheric phenomenon linked to solar flares is called the northern lights.
the north pole
We said that the northern hemisphere contains the boreal pole or north pole . It is the opposite pole to the south pole, both coinciding with the planet 's axis of rotation.
At the north pole (or North Pole , with capital letters, when the region is referred to) is the Arctic Ocean . The polar fox, the ringed seal and the polar bear are some of the animals that live in this area characterized by extreme cold.
It is interesting to note that the North Pole and the part of the surrounding Arctic Ocean do not belong to any country, according to international law. The United States (the state of Alaska ), Canada , Denmark (the island of Greenland ), Norway and Russia are the nations with jurisdiction in its surroundings.
The Northern Lights
A polar aurora is a luminous phenomenon that can be seen near the poles, generated by electrically charged particles that come from the Sun 's eruptions . The polar lights that occur in the northern hemisphere are called the northern lights .
Before moving forward, it must be taken into account that a polar aurora is a meteor (that is, an atmospheric phenomenon). In this case, it is caused by electrically charged particles emanating from solar flares or flares. These eruptions , in turn, consist of the sudden and high-intensity release of electromagnetic radiation.
Returning to the idea of the northern lights, they can be seen in the night sky near the north pole as a luminescence . With the northern lights, rays, spirals and stripes of different colors appear that move or tremble in the sky .
