We are in a century in which education, knowledge, professional skills will play a decisive role in the fate of a person. Without knowledge, by the way,

all complicating will simply can not work, to benefit ... A person will make new ideas, think about what the car will not be able to think about. And for this, there will be more and more general intelligence of a person, its ability to create a new one and, of course, the moral responsibility that will not be able to carry the car ... A person will fall on a person, and the most difficult task to be a person is not just, but a man of science, a man morally responding For everything that happens in the age of cars and robots. General education can create a person of the future, a person's creative, creator of all new and morally responsible for everything that will be created.

The doctrine is that now you need a young man from the very old age. You always need to learn. Until the end of the life, not only taught, but also studied all the largest scientists. Change to learn - you can not learn. For the knowledge all grow and complicate. It is necessary to remember that the most favorable time for teaching is youth. It is in the youth, in childhood, in adolescence, in his youth a person's mind is most susceptible.

Hello not to waste time on trifles, to "rest", which sometimes tires more than the hardest job, do not fill your light mind with muddy flows stupid and aimless "information". Take care of yourself for the teachings, to acquire knowledge and skills, which only in youth you are easy and quick.

And here I hear the grave sigh of a young man: what kind of boring life you offer our youth! Just learn. And where is the rest, entertainment? What do we, and not rejoice?

No. Acquisition of skills and knowledge is the same sport. Teaching is hard when we do not know how to find joy in it. We must love to learn and form recreation and entertainment to choose smart, who can also teach something, to develop some abilities in us that will be needed in life.
Learn to love to learn!

The social structure of society is not frozen; It constantly occurs in oscillations and movements, i.e. It is characterized by social mobility. Social mobility is a change in the social group or an individual of his social position. The term "social mobility" was introduced into the sociology of P. A. Sorokin, who considered social mobility as moving along the social staircase in two directions of the vertical - movement up and down, horizontal - movement at the same social level. In periods of social changes, mass group mobility is observed. In stable periods, social mobility increases at the time of structural restructuring of the economy. In this case, an important "social elevator", which ensures the vertical mobility of the ascending species, is an education. Social mobility is a fairly reliable indicator of the level of openness or closedness of society. In modern society, social mobility generates a phenomenon of social marginalness. Mind is a concept characterizing border, intermediate, standing at the turn of cultures of phenomena, social constituents and statuses ... Marginalization implies a break, loss of objective affiliation to some social community without subsequent entry into a different community or Without full adaptation in it. A marginal is a person relevant to two different groups, not belonging to any of them completely ... a subjective representation of the marginal about himself and his objective position is contradictory: it is put in the situation of struggle for survival. Therefore, a marginal person has a number of characteristic features: anxiety, aggressiveness, unjustified ambition. The social behavior of the marginal creates difficulties of both the person himself and the people communicating with him. For a long time, marginality was assessed in sociology negatively. Recently, sociologists have changed their attitude towards it, seeing a positive side in this social phenomenon. (Minaev V.V., Arkhipova NE., C1. Relying on the text, indicate a feature determining the essence of social mobility. What are the main directions of social mobility? C2. Under what two social conditions, according to the authors , Education acts as an important "social elevator"? Explain any of these conditions. Cas3. Whom the authors call the marginal? Give the definition and give a support for the knowledge of the social science and the facts of public life. C4. Recently, as the authors noted, sociologists saw a positive side in marginalness.

Islands differ in size: from small coral unnamed to Australia - a huge continent. Animal and vegetable world of the islands are separated from the main part of sushi with water. This means that island plants and animals are isolated from other plants and animals.

How are the islands are created?

Islands are created in two ways. The first is when the sushi part is separated from the main land. For example, Madagascar and New Zealand have formed so 20 million years ago. From the very beginning there were plants and animals.

Another way to form the islands is when volcanoes that are at the bottom of the sea are throwing out so many solid rocks that new islands are formed in the ocean. So formed Galapagos and Hawaiian Islands. On such volcanic islands, there was no live life at the time of their occurrence.

Guests of the islands

Most of his life, sea birds spend in the sea, feeding fish. They appear on the islands in the midst of the ocean to arrange nests where there are few predators threatening chicks.

Fregates have big wings and little legs. They attack other birds, make them pull them off and then dive and eat it.

Albatrosse possess the biggest among the birds of the wings. The wandering albatross spends most of the time in the air. It feeds not far from Australia, and the nests go on the islands of the South Atlantic.

Sinogeniya Olushi nest on Earth islands of the southern Pacific. They feed on fish and swim well.
Upcomgte nests, pulling out the deepening in the shores. The color of the beak in males remains bright only at the time of attracting females.

New Islands

Most of the new islands - volcanic origin. Sometime, the volcano stopped the eruption and turned simply into the rocks. They gradually appeared soil, the plants rose and animals came.

Winds and ocean waves destroy rock rocks and turn them into very small pieces. This process is called erosion. Animals that fed into the sea, such as sea birds, seals and sea lions, were the first to appear on the islands. They multiplied there, where there were no predators. Their discharges gradually collapsed, mixing with solid particles, and formed the soil.

Plants of new islands

Over time, soil appears on the new islands and plants can grow. They are formed by seeds with which plants apply. Wind, water, as well as birds and other animals tolerate seeds. Some plants have seeds covered with numerous hooks. They are transferred, clinging to the feathers of birds or animal wool.

Other plants, such as figs, give fruit in which seeds are located. Animals eat fruits, and then the seeds fall along with feces. Seeds of plants such as orchids are so easy that we are spread by the wind. In other plants, for example, the thistle, the seeds are cold and are equipped with filament paratroopers that the wind picks up. Coconuts are seeds of palm trees. Their shell is waterproof, so they are calmly transferred by the sea.

Animal vegetarians can survive if they appear on the islands where many edible plants. This is the second after sealing and seabirds of animals that are justified on the new islands.

Animals of new islands

In order for the types of animals to survive on a new island, the first animal arrived on the island must be able to reproduce (the production of the cub), so he needs to wait for a pair. Animals that can fly, such as birds, bats and insects, can cross water spaces. They easily reach the shores of new islands and begin to multiply.

Terrestrial animals, such as proteins, iguana and toads, cross the oceans only by chance, if they were cleaned into the sea. To new islands, they get extremely rare. It is assumed that the new type of animals appears in Hawaii (Islands in the Pacific Ocean) only once every 12,500 years.

Islands are small areas of sushi, which are surrounded by water from all sides. Man has always been interested in how they are formed and why they have such a variety of form and appearance. Some of them are only rock formations, while others have incredible features of flora and fauna, which was formed here as a result of long-term isolation.

The question is how the islands appear, it has already been considered long ago by scientists and answers can be found not one and not even two. The reasons for the emergence of these areas sushi are quite a lot. One of the main causes of the island is the long process of the movement of the earth's crust, as a result of which one of its sites is "protruding", forming a fold on which the island is formed.

But there are both opposite processes that make it clear - how the islands located as part of England and Ireland. The fact is that at this places a thousand years ago there was a sushi, which united England with the rest of Europe, but as a result of tectonic processes, the earth's edge in this place was sank and separated the land plot from the rest of the mainland. It is not necessary to think that this process was instant, to complete the process, the nature took long decades.

So the archipelago appeared- as a group of islands associated with a single location and proximity. In some cases, the formation of the island (in the fiery belt) can be observed in real time. This concerns, above all, islands of volcanic origin. In places where the bottom is located near the surface of the ocean, volcanoes can erupt, throwing a hot lava that becomes the basis for the future island.

The eruptions should be thought of to learn to live on the island, as the volcanoes that have formed them can "wake up" at any time. Although in case you want to choose a safe place to live, you can choose the island that was created by the work of billion of small marine creatures. Coral polyps are engaged in this construction work, creating real works of art in places of cluster. And the basis for the island is their limestone shells.

The secrets of the formation of the islands, contain answers to something - how the Easter Island was settled, which was once part of more extensive lands. And if we talk about coral reefs, then for the creation of such islands, thousands of years and warm tropical seas are required. Shelovka also has an impact on nature, creating artificial islands on a floating basis under overpopulation. Nature has many more secrets, solve which only future generations of scientists can solve.
