Nature in autumn: a series of amazing metamorphoses

Nature in autumn changes beyond recognition. With the advent of September, leaves and grasses begin to gradually turn into golden tones, and cool fogs increasingly meet people in the mornings. Such metamorphoses captivate the eye of a curious observer and remind that everything in life moves in an invariable circle.

However, how often does a person think about why this happens? Why does nature change so much in autumn? What causes leaves to turn yellow? Or why frost falls on the still green grass? Well, let's try to find answers to these questions.

Edge of golden colors

The first changes in nature in autumn begin with the fact that grass and leaves change their green color to yellow and red. Few people know the reason for such changes, but it was in the school curriculum.

As you know, the green color of the leaves is given by chlorophylls, which are contained in plant cells. But, alas, for their normal functioning, a lot of heat and sunlight are needed. And since with the advent of autumn the days become shorter, and the temperature graduallydecreases, the chlorophylls die one by one.

But the most amazing thing is that this process benefits the trees. Indeed, otherwise, with the advent of winter, they would have been too tight. The reason for this is snow adhering to the leaves and capable of breaking even the strongest branches. In particular, this is why nature sheds everything unnecessary in autumn, including leaves.

First silver shoots

Toward October, the first frost begins to appear on the grass. It is especially noticeable in the morning, this is due to the fact that the autumn sun at such a time does not yet have time to warm the air. But how does frost form?

It's all about the atmospheric moisture that condenses on the grass. In the summer, this phenomenon could be observed as morning dew. However, in autumn, when the air is already cool enough, this moisture freezes, thereby turning into small crystals of frost.

Wild Animals

What other changes does nature undergo in autumn? Along with plants, many living beings go into hibernation. So, all insects are looking for deep holes for themselves, so that severe winter frost cannot reach them. The same goes for reptiles, who seek to find a secluded place for themselves.

Many birds also do not like cold weather, and therefore, closer to the middle of October, they gather in flocks and go to warmer climes. Only the most adapted species, such as bullfinches, crows or sparrows, remain wintering.

Mammals also feel the imminent arrival of winter, so in autumn they are activelygain weight so that the fat layer does not allow them to freeze in winter.
