The four seasons of the year are a natural phenomenon that expresses a certain beauty. In addition, these are times of the year when where climatic events of scientific interest occur and everyday. Undoubtedly, the seasons of the year are part of human history, possessing different meanings.
According to the site or hemisphere, the seasons may or may not present themselves fully. Depending on the position, they also occur in a transitional or inverted cyclic manner respectively. Whatever the premise, the seasons of the year cause a bit of curiosity and mystery. How are they produced?

Where do the four seasons of the year come from? Discover the whole truth!
It is very common to have the belief that the four seasons of the year are due to the distance of the Earth from the Sun. It is partly true, but the emergence of these different times of the year is due to a much greater cause. .
In general, the stations are secondary to the tilt of the Earth's axis. As the planet revolves around the sun, it describes four primordial positions that give rise to the seasons. They, better known as spring, summer, autumn and winter, occur in that order or vice versa, according to the hemisphere.

Each season of the year is comprised of solstices and equinoxes, being two for each. They are separated for an approximate time of 3 months from each other, causing the beginning and end of a certain season.
Also, the four seasons of the year they are characterized by certain properties and climatic characteristics. Each of them is extensively studied by climatology, because they are a guarantee of their own and extraordinary natural phenomena.
Due to the tilt of the Earth's axis, as it goes through its normal orbit, certain parts are more or less far from the sun. In that sense, there will be occasions where the north pole will point and be closer to the sun. Right at that time, it means that the summer solstice has begun or the summer season has begun respectively.
For its part, when the south pole is affected by the sun's rays, means that it is summer at that point. In short, while it is summer in one hemisphere, the opposite season (winter) occurs in the other.
Approximately how long are the four seasons? Encourage your curiosity!
As mentioned above, according to the tilt of the planet Earth, the four seasons occur in reverse. That is, when the Earth orbits the sun, the tilt of its axis causes one hemisphere to be closer to the star.
For this reason, while in one hemisphere it is summer, in the other it will be winter and vice versa. The tilt of the Earth prevents the four seasons from appearing symmetrically on its surface in equal parts.
With respect to the northern hemisphere, the season that initially appears is spring. For its part, in the south pole, as the first link, the autumn season appears. Likewise, as already mentioned, they will also depend on the solstices and the equinoxes.
the equinoxes, They are responsible for both spring and fall. While the spring equinox occurs at one pole, the autumn equinox as such occurs at the other. Between one and the other, there is a period of approximately 6 months throughout the year.
For its part, the rest of the four seasons of the year, that is, both winter and summer, depend on the solstices. In short, it will be the summer solstice at the north pole, when the south pole sets the winter solstice. And, like its predecessors, there is a separation of 6 months between the two.
What are the characteristics of the four seasons? Learn more about them!
The four seasons have a specific biotype, accompanied by very own characteristics of each one. In addition to climatic changes or the type of environment they describe, it is also important to highlight the duration of sunlight.
the flowery spring
It begins with the spring equinox, being a characteristic season for the temperate climate. However, spring varies between low, high or mixed temperatures, according to the passing of the months.
During this period, the tilt of the Earth brings one of its poles directly closer to the sun. That way, sunlight lasts longer, lengthening the days progressively. In short, the days are longer than the nights.
the hot summer
Of the four seasons, summer is the hottest period of the year known. In certain areas of the Earth, the temperature during the summer can exceed. 45 degrees centigrade. It occurs after spring, with the beginning of the winter solstice and ends with the establishment of the autumnal equinox.
It's the time of year more prone to fires, drought and arid climates, where the rains are practically scarce. The tilt of the Earth, regardless of the specific pole, reaches its closest approach to the sun. For this reason, the length of the days becomes even longer and the nights even shorter.
balance in autumn
Once the summer solstice ends and the autumnal equinox begins, the warm temperatures begin to drop. Autumn is the season prior to winter, subsequent to summer, being synonymous with temperate climates as well as spring.

It is the period of the year, where the natural cycle of plants begins to end. As a consequence, its leaves fall or fade to an orange appearance, giving rise to the characteristic fall foliage.
the cold winter
The culmination of the cycle of the four seasons is determined by the winter solstice. It is the time of snowfall, hailstorms and torrential rains, where the temperature tends to drop.
As winter approaches, Earth tilts its axis away from sunlightso that the days become shorter. In autumn, this sensation begins to be felt, but it is even more accentuated during winter. As a consequence, low temperatures intensify, resulting in the typical foliage of this season.
