8 interesting facts about autumn

In one year, Keats calls it "season of mist and mellow fruit", and in autumn it is a season known for turning leaves, harvesting, cooling down the night and becoming dark. But why does the color of the leaves change and when will autumn begin? Let's see the answers to these and more interesting facts.

You can say that autumn starts on two different days. The fall defined by the orbit of the earth around the sun begins at the midnight minute of September 22 or 23.

However, to record climate data, it is important to set a comparable date. Therefore, the weather always starts on September 1.

One of the most wonderful signs of autumn is the rotation of the leaves. A short day is a sign that trees are preparing for the winter.

In winter, there is not enough light for photosynthesis, so as the whole autumn season becomes shorter, the trees begin to close their food production system and start to reduce the chlorophyll content of the leaves.

Chlorophyll is a chemical that turns leaves green, but as leaves fall, other chemicals become more prominent in the leaves.

These are bright autumn amber, red and yellow reasons. Responsible chemical substances are flavonoids, carotenoids and anthocyanins

Did you know that these chemicals are the same color as carrot (beta carotene) and egg yolk (lutein)?

According to a survey by Journal of Aging Research, we found that babies born in the fall are more likely to live to 100 years than babies born in other years.

The word equinox comes from Latin equi (meaning equal) and nox (meaning night).

After the fall dividing point, it is clear that night begins from this point and it is longer than night until it reverses at the vernal equinox point.

Generally, autumn is always falling on September 22 or 23, but this is not always the case.

Since the Gregorian calendar is not perfectly symmetrical with the orbit of the Earth, autumn will occasionally fall on September 24th. This took place at the end of 1931 and then in 2303.

In Greek mythology, autumn began when Persephone was kidnapped by Hades as the queen of the underground world. In the trouble, Persephone's mother, Demeter (harvest goddess), caused all the crops on Earth to die until the daughter was allowed to return. And I showed Spring.

We usually regard "autumn" as the North American version of the word "fall", but until recently it was widely used in the UK.

This sentence shortened very common leaf leaves in England in the first 17 th century.

The word autumn was entered in English from the French car until the 18th century.

A small discourse has fallen into an identity crisis, and degeneration is one of them. Both autumn and autumn were born in the UK and moved to the United States. But so far, autumn has been a popular term for quite a while. Actually, until 1755 when Samuel Johnson first entered an English dictionary, the autumn of "fall" was not in the dictionary. Why did not Pickering's friends reveal further detail to us - but by the middle of the 19th century American dictionary editors thought that fall is totally American. Autumn is still occasionally used in British English speaking countries, but usually there are only a few regular phrases such as spring and autumn.

Perhaps this is related to the fact that autumnal equinox (for the first day of autumn, those who like to talk with non-spies or amateurs) is usually my birthday on 23rd September. Anyway, I really like everything about fall, please ban those sneaky brown stray leaves, slide me and see all the damn cars and pedestrian unhappy death . But if I could return it to joy and general publicity in autumn then the second season from the end of this year will start a lot of my favorite things in my life. From my wardrobe, cosmetic, nail selection, my food, drinks, visits to the park, and very praised nature
