reference Information
The Russian coal industry is in a state of economic crisis. What are the general
economic, social, environmental problems are facing regions where coal
industry is important? How to solve these problems? Let's do a little
journey beyond the Arctic Circle, to the region of Vorkuta.
The Pechora coal basin is located in the north of the Komi Republic, in the Vorkuta region. Started actively
developed during the Great Patriotic War. After the war, coal mining capacities were here
have been enlarged, new mines have been built, but in general, the basin already requires large funds for modernization.
About 8% of Russian coal is mined here, and it is of high quality. However, great prospects
does not have a pool due to the high cost of coal (since it is located beyond the Arctic Circle, miners
receive "northern allowances", their salaries are 2-3 times higher than in other coal basins).
But the reduction of coal production is more difficult to implement here. If coal mines are closed in some
or other coal basins, then in the same cities and towns you can create new industries in order to
take on the miners who have lost their jobs. To create new production facilities in the Arctic is economically
inappropriate - they will be unprofitable.

Grading
Didactic material for the lesson
Topic: "Establishing the relationship between the components of nature on the example of natural zones."
Objective:
Progress.
Task: Using the maps of the atlas, textbook art. 296-297 complete the table.
1. How do differences in climate affect the vegetation of forest zones?
In the taiga zone, where the climate is colder, especially in Siberia, vegetable world less diverse than in the European part of the taiga. To the south, in the zone of mixed and broad-leaved forests, where the climate is temperate, warmer, the species composition of plants is very diverse. And in the more humid tropical and equatorial forests, there is an even richer flora.
2. It is known that more plant mass is formed in forests than in the steppes, but forest soils are poorer than chernozems. Why?
Soil formation is influenced by several factors. Most strongly - climatic features and flora. The forests are rich in flora, but the amount of precipitation is also significant. Dissolved particles are washed out with water and carried away to lower soil horizons. As a result, podzolic and gray forest soils have formed in the forests. In the steppes, vegetation is represented by grasses, but the amount of precipitation is small, which means that dissolved substances remain in the upper layers of the soil. In this natural zone, chernozems have formed - the richest soils in the world.
3. On the example of one of the forest zones of Eurasia, show the relationship between the components of nature.
Natural zone - coniferous forests (taiga). Thanks to its thick forest cover, the taiga has become a refuge for many animals, and is considered one of the richest areas in biodiversity.
Tundra zone - poor vegetation, harsh natural conditions. A low level of biodiversity, but animals that have adapted to life in such harsh conditions have learned to survive and reproduce.
A temperate type of climate has formed in the natural zone of the steppes. High air temperatures and a small amount of precipitation contributed to the formation of predominantly herbaceous vegetation. Due to the small leaching regime, chernozem soils were formed. Steppe animals adapt to life in such conditions. It will be mostly rodents. There are few species of these animals, but their number is significant. Ungulates that can travel considerable distances will also live here. They are hunted by predators such as foxes, wolves. A large number of birds that feed on plant seeds or prey on rodents.
4. Why do natural zones in Eurasia change not only from north to south, but also from west to east?
Due to the monsoon circulation of air masses.
5. In what natural area of the mainland is your school located?
Zone of mixed forests.
6. Name the characteristic plants and animals of this zone.
Pines, oak, elm, linden, maple, birch, aspen, poplar. Wolves, hares, roe deer, hedgehogs.

How and why did this situation come about? In the last decades of the 20th century and at the beginning, Russia experienced difficult times, primarily in the economy. Many people lived in extreme poverty, with many businesses idle or operating at low capacity.
"Economic regions of Russia" - National composition: mostly Russians (Orthodox Christians). The soils are podzolic and peat-bog. Washed by the waters of the Northern Ice Ocean. Forests occupy 3/4 of the territory. Animal husbandry (dairy and meat) prevails over crop production; reindeer breeding, pig breeding, poultry farming. Urbanization coefficient - 83%.

"Natural and economic zones" - In the direction from north to south they change. Natural economic zones of Russia. What is a natural economic zone? L.S. Berg is a scientist of extraordinary breadth of views, geographer and biologist. The natural economic zones of Russia are divided into. What is zonation? V.V. Dokuchaev is a great Russian geographer. It is clear that in the northern regions the sun's rays fall obliquely on the Earth.
At the moment, there are practically no places left on Earth where a human foot has not set foot. First of all, we will talk about its influence on natural complexes. This is due to a number of factors. First, the number of people on the planet is increasing. In order for the settlement to occur evenly, it is necessary to constantly work on the development of new lands. Forests are cut down, crops are cultivated, representatives of the local fauna are killed or expelled.
Secondly, the development of human technology cannot be stopped. Thanks to man, he can penetrate with his gaze into the depths of the universe, he can penetrate deep into the abyss of the seas and oceans, he can explore the hottest and coldest places on the planet. Take, for example, the discovery of America by Columbus. If not for the development of merchant shipping, such a discovery would not have been possible. A person, pursued by a sense of curiosity, gets to where he has not been before, and tries to survive in new places. This does not occur without anthropogenic influence on environment.
The third and most significant factor is the development of industry. Thousands of factories around the planet emit thousands of different toxic substances into the atmosphere, land and water, which pollute the environment improperly. After all, the Earth is also one big. Not to mention how a specific piece of the Earth on which industrial enterprises are located.
Interaction of the components of the natural complex
In addition to human influence, constant processes take place inside them, which dynamically change and transform natural complexes. These processes are associated with those interrelated components that are inherent in any natural complex. These are relief, water, soil, climate, vegetation and wildlife. Any change in time of any of these components inevitably leads to a change in all the others.A living example is the era of the dinosaurs. In prehistoric times, the whole Earth was inhabited by these amazing animals. If it were not for the fall of the meteorite and the abrupt climate change all over the planet caused by this event, no one would have said what modern natural complexes would be like and what a person would be like on Earth.
Another example that everyone is talking about is the destruction of the ozone layer of the atmosphere. Due to excessive emissions of greenhouse gases by industrial enterprises, the planet has practically no means left from the ultraviolet radiation of the Sun. This leads to a gradual change in climatic conditions throughout the Earth and an increase in the level of the world's oceans.

1. The Pacific Ocean is the largest and oldest of all oceans. its area is 178.6 million | cm2. it can freely accommodate all the continents and islands combined, which is why it is sometimes called the great one. it is located between the continents of Eurasia and Australia in the west, North and South America in the east, Antarctica in the south. 2. The study and development of the Pacific began long before the appearance of written mankind. junks, catamarans and simple rafts were used to navigate the ocean. The expedition of 1947 on a raft of logs "kon-tiki" under the leadership of the Norwegian Thor Heyerdahl proved the possibility of crossing the Pacific Ocean in a westerly direction from the central part of South America to the islands of Polynesia. Chinese junks made trips along the coast of the ocean in Indian Ocean. 3. The vast expanses of the Pacific Ocean lie in all climatic zones, except for the polar ones. several areas of high and low pressure, winds form, monsoons blow in the northwest of the ocean. typhoons often blow through. properties largely depend on the climate water masses. the temperature of surface waters is measured from -1 s (in the north) to +29 s (near the equator). precipitation over the ocean over evaporation, so the salinity of surface waters in it is somewhat lower than in other oceans. the warm waters of the ocean contribute to the work of corals, of which there are many. A large reef stretches along the eastern coast of Australia. it is the largest "ridge" created by organisms. 4. economic activity of man to severe pollution of some areas of the Pacific Ocean. this was especially evident off the coast of Japan and North America. stocks of whales, a number of valuable species of fish and other animals have been depleted. some of them have lost their former commercial value.

Africa: the coordinates of the extreme points is the second largest continent on our planet. it covers an area of 30 million square kilometers. Africa is connected to Eurasia by the narrow Isthmus of Suez. 8 thousand kilometers - it is at this distance that the mainland of Africa stretches from north to south. the coordinates of the extreme points of the continent are as follows: the northern one is Cape Ras-Engela (37.21 degrees north latitude). southern - Cape needle (34.51 degrees south latitude). 7.5 thousand kilometers - the distance between the western and eastern outskirts of such a continent as Africa. the coordinates of the extreme points of the continent are as follows: western - Cape Almadi (17.33 degrees west longitude). eastern - cape ras-gafun (51.16 degrees east longitude). The length of the coastline of the mainland is 26 thousand kilometers. this is small for a continent of this size. the reason is that the coastline of Africa is poorly indented. it should also be noted that the extreme points of Africa have other names. for example, Cape Agulhas is sometimes called Cape Agulhas. and Cape Ras Angela is sometimes called Cape Blanco. therefore, in the scientific one can also find these toponyms. Africa's position is unique. the fact is that the equator crosses this mainland almost in the middle. This fact leads to two important consequences.

Definition by synoptic map weather features for various points. Making weather forecasts
Complex phenomena occurring in the troposphere are reflected on special maps - synoptic, which show the state of the weather at a certain hour. Scientists discovered the first meteorological elements on the world maps of Claudius Ptolemy. The synoptic map was created gradually. A. Humboldt in 1817 built the first isotherms. The first weather forecaster was the English hydrographer and meteorologist R. Fitzroy. From 1860 he gave forecasts of storms and compiled weather charts, which were greatly appreciated by sailors.

reference Information
The Russian coal industry is in a state of economic crisis. What are the general economic, social, environmental problems facing the regions in which the coal industry is important? How to solve these problems? Let's make a short journey beyond the Arctic Circle, to the Vorkuta region.
The Pechora coal basin is located in the north of the Komi Republic, in the Vorkuta region. It began to be actively developed during the Great Patriotic War. After the war, coal mining capacity was increased here, new mines were built, but in general, the basin already requires large funds for modernization. About 8% of Russian coal is mined here, and it is of high quality. However, the basin does not have great prospects due to the high cost of coal (since it is located beyond the Arctic Circle, miners receive "northern allowances", their wages are 2-3 times higher than in other coal basins).
But the reduction of coal production is more difficult to implement here. If coal mines are closed in any other coal basins, then in the same cities and towns new industries can be created to take on miners who have lost their jobs. It is not economically feasible to create new production facilities in the Arctic - they will be unprofitable.
3. Give a description of the Pechora coal basin, presenting the results of the work in the form of a table.

3. Make a conclusion not only about the presence of a relationship between the components within the complex, but also about their dependence on geographical location the area where the complex is located.
To compare the natural complexes of two different natural zones of South America (moist equatorial forests and shrouds) and draw a conclusion about the relationship between the components within the complex and the geographical location on which this natural zone is located. The results of the students' work are presented in the form of a table.
4. Sources of knowledge on the basis of which the work is performed:
Students analyze maps of the atlas: a physical map of South America, climatic, natural zones, a soil map and the text of the textbook "Geography of continents and oceans" - V.A. Korinskaya, I.V. Dushina, V.A. Shchenyov No. 40 - 44.
5. Methods of cognitive activity of students:
I propose to perform this work on the basis of an analysis of the atlas maps and the text of the textbook in the form of a comparison of two natural complexes in South America. The results of the work and the conclusions drawn by the students are drawn up in the form of a table. An analysis of the table makes it possible for students to show the difference between natural components and natural conditions (relief, climate), which affect the qualitative content of the components, depending on the geographical location of the territory on which the complex in question was formed.
6. Task for students:
1. To acquaint with the application of the textbook "Geography of continents and oceans" by V.A. Korinskaya, I.V. Dushina, V.A. Shchenev on page 313 "How to compare correctly"
2. Compare the natural areas of South America: humid equatorial forests and savannahs according to the following plan:
a. Geographical position.
b. Natural conditions: a) relief b) climate.
in. Natural components: a) soil b) inland waters c) flora and fauna.
d. Make a conclusion about the interrelationships of the components in the complex and their dependence on geographical location.
7. The planned result of the work done by students.
Natural conditions and natural components of the complex | Moist equatorial forests | Savannah |
1. Geographic location | It is located on the Amazonian lowland and on the adjacent eastern slopes of the Andes, as well as in the northern part of the Pacific coast in the region of the equatorial climatic zone. | It occupies the Orinok Lowland and most of the Guiana and Brazilian Highlands. |
2. Natural conditions | ||
A) relief | Amazonian lowland | Orinoco Lowland, Brazilian Plateau, Guiana Highlands. |
B) climate | Equatorial, hot and humid all year round. | Subequatorial, dry and wet (December-May) periods are clearly expressed, partly in the tropical. |
3. Natural ingredients | ||
A) soil | Red-yellow ferralite | Red ferralite |
B) inland waters | The Amazon River and its tributaries | The Orinoco, Parana, Vdp. Angel, vdp. Iguazu. |
B) vegetation | Ceiba, melon tree, chocolate tree, palm trees, ficuses, hevea | Cereals and legumes, palm trees, mimosa, bottle tree, quebracho. |
D) animal world | Jaguar, capybara, anaconda, hummingbird, toucans, parrots | Deer, pikari pigs, armadillo, crocodiles, jaguar, puma, rhea ostrich |
Conclusion - The zone of moist equatorial forests occupies a large area in South America due to the presence of extensive lowland plains. Due to the humid climate and the rich iron compound, the soils take on a reddish tint. Hence the name of the soil - red ferralitic. Arriving in large numbers organic matter decompose to the end, and do not accumulate in it, and an abundance of moisture leads to continuous washing of the soil to a great depth. The relief is flat and since this natural area is very humid, it is not surprising that the most full-flowing river in the world, the Amazon, flows here. Character traits humid equatorial forests of South America (selvas): they are evergreen, diverse in species composition, multi-tiered, flowering and fruiting year-round. In some places, the forest thickets are impassable and the sunlight barely penetrates through the dense foliage. In such a forest, even during the day it is gloomy. Therefore, many animals live in trees or spend the night in trees.
Savannas in South America occupy a smaller area. Due to the two seasons of dry and wet climate, the soils are also easily washed, but here the vegetation cover consists of various and leguminous plants. In the dry period, due to lack of moisture, the vital activity of microorganisms slows down and plant litter does not decompose completely, and therefore humus accumulates. During heavy rains, nature comes to life. Animals, like plants, adapt to dry and wet periods. Rivers also have a seasonal nature of the regime, or are full-flowing and flood the surrounding flat spaces, or become very sweet during the dry period. The rivers flow from the plateaus (Guiana, Brazilian) and therefore there are many rapids and waterfalls - Iguazu, Angel. Thus, these are very different, unique natural areas located in South America.
