The article tells about what a mantle is, what values this word has, in particular it says about the planetary mantle.
In any living language, spoken by people,if it develops, over time, under the influence of one or another circumstance, words appear that have several semantic meanings. They are inherent in them initially, or similar things happen with time. As an example, you can cite zamok and zamok, as well as the word "language". This is the organ in the person's mouth, and some kind of elongated terrain, and a prisoner of war who can provide valuable information.
And one of these words is "mantle". What is the mantle? When it is mentioned, different things come to mind: clothing, the structure of the planetary crust, and so on. In the article, we will analyze the meaning of this word, but about everything in order.
In the bowels of our planet are constantly occurringvarious reactions, notice them with the naked eye, by itself, it is impossible, but their consequences people always felt. Their most striking manifestations are earthquakes and their "satellites": tsunamis, volcanic eruptions and so on. Conditionally, the internal structure of our planet can be divided into three layers, this is the bark, mantle and core. So what is the mantle of the Earth?
As already mentioned, the mantle is a layer thatIt occurs only in the terrestrial planets and is located between the surface crust and the inner core of the celestial body. According to scientists, it is formed as a result of processes of separation of metal parts from the primary substance of the planet and leaving them in depth, and the products of melting of such substances as a result form the bark of the body. So now we have found out what the mantle of the Earth is. On our planet it consists mainly of peridotites.
As mentioned earlier, the planetary mantlenot only for the Earth, it has almost all other known celestial bodies of the so-called terrestrial group - the Moon, Venus, Mars. But Mercury was less fortunate: as a result of a strong meteoric bombardment, the entire crust and a significant part of the mantle were destroyed.
On Venus, however, the mantle differs from the mantle muchgreater temperature, and instead of tectonic plates in the bowels of our heavenly neighbor there are plume currents. So we understand the question of what a geological mantle is. Now let us consider other meanings of this word.
Mantle is also a piece of clothing, it is veryancient, was used by our ancestors millennia ago. But in our time it is used mainly as a symbolic or ritual apparel, for example, as a judicial robe. Surprisingly, such a mantle is considered the official garb of some employees of the judiciary system of many countries.
Such clothes seem to hide all humanand weak, elevating the judge or advocate over worldly passions and strong emotions that can affect the outcome of the matter. And black color also symbolizes impartiality. Now we know what mantle is like as an official form of apparel for ministers of special organs.
Such an element of vestments is also part of theThe academic clothes of graduates of many universities and teachers of academies and other educational institutions. True, such a tradition does not exist in all countries. It dates back to the Middle Ages, when the church had a strong influence on society, and most institutes and other educational institutions originated from church schools. So we have analyzed yet another aspect of the question of what is the mantle, the definition of this word and what it means.
In zoology, the mantle is a special fold of the skin that surrounds a part of the body or the whole body. We use the term in relation to mollusks and barnacles.
In the days of pre-revolutionary Russia in the textbooks of biology, the mantle was often called epanchs, but in our time this term is obsolete and is no longer used.</ p>
