Description of the presentation by individual slides:

River - Lena and the mighty Yenisei The largest rivers of Siberia, Lena and Yenisei, are rich in energy and fish. A huge amount of minerals are mined on the banks of the rivers, and large enterprises have been built. Timber rafting is carried out along the river towards the seas of the Arctic Ocean. 8 slide The rivers of the Atlantic Ocean basin are a dense river network and many lakes. Food in the west (Seine, Rhine) is rainy (marine climate), the rivers do not freeze and are navigable all year round. In the east there is a mixed diet (Elbe, Oder, Vistula), they do not freeze for long, and there is high water in the spring. Navigable in the warm season. Rivers of the basin

Description of the presentation by individual slides:

The Danube River (the ancient name Istr) on its way from its source in Germany to its mouth in the Black Sea flows through the territory of 10 countries: Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Romania, Moldova, Ukraine. The fate of many European states was decided on its shores. Where it flows: The Danube is formed by the confluence of the Breg and Brigach rivers, near the city of Dronauesching in Germany at an altitude of 678 m. It is the second largest river in Europe after the Volga. On its banks are located such European capitals as Bratislava, Vienna, Budapest, Belgrade. In Romania it flows into the Black Sea forming a large delta. Even in ancient times, the Danube served as a transport artery. Length of the Danube: 2860 kilometers.

Description of the presentation by individual slides:

Tributaries of the Danube: Iller, Lech, Isar, Inn, Enns, Morava, Raba, Vag, Gron, Ipel, Drava, Tisa, Sava, Morava, Iskar, Siret, Prut. other. Intensive use of the river has disrupted the ecological balance and the number of fish in the Danube has decreased significantly. You can also add others here ecological problems: drying out of floodplain forests, extinction of animals that traditionally lived on the banks of the river. Power supply: The Danube has different power sources. The main source of water is melted snow from the mountains. Also important role rain and groundwater play. Freezing: High water occurs in spring and summer, from late February to August. The Danube has the least water in September and October. The river does not freeze every year (in January-February).

Description of the presentation by individual slides:

The Rhine River (translated from Celtic as “flow”) is also one of the most significant rivers in Europe. The length from source to mouth is 1320 km. The area of ​​the drainage basin is 251,800 km. sq. Where it flows: The Rhine originates in the Alps at an altitude of 2000 meters above sea level. The river flows through the territories of such Western European countries as: Switzerland, Liechtenstein, Austria, Germany, France, and the Netherlands. It is formed from the confluence of two mountain rivers and in the upper reaches it has a mountainous character. After the city of Basel, the river abruptly changes the direction of its flow and rushes north. The area between Basel and Lake Constance is called the Rhine Mountain. located below sea level. Before flowing into the North Sea, the Rhine forms a delta, splitting into many branches.

Slide 13

Description of the presentation by individual slides:

Tributaries: Neckar, Main, Ruhr, Aare, Moselle. Cities on the Rhine: Arnhem, Dusseldorf, Cologne, Bonn, Mainz, Strasbourg, Basel and others. Canals connect the Rhine with the Rhone, Elbe, Marne and Weser.

Slide 14

Description of the presentation by individual slides:

Rivers of the Pacific Ocean basin: Amur, Yellow River, Yangtze, Mekong. Almost all rivers are predominantly fed by rain. The summer monsoons bring rains that cause violent river floods. Amur - rain-fed (summer monsoon), floods of the river and its tributaries, freezes in winter, navigable in summer. Flows into the Sea of ​​Okhotsk. The Yellow River (“yellow river”) originates in village of Tibet highlands. In the upper reaches there is a mountain river, fed in summer by mountain snow. Further it flows along the Loess Plateau and enters the Great Chinese Plain. Powered by rain (monsoon). Flowing into the Yellow Sea, it forms a delta, which increases by 300m annually. water is used for irrigation.

15 slide

Description of the presentation by individual slides:

Rivers of the Pacific Ocean The waters of the Yellow and Yangtze rivers are navigable. They are used to irrigate fields. These rivers flood heavily during rains and lead to significant destruction of roads and residential buildings on the banks.

Slide 17

Description of the presentation by individual slides:

Yangtze Yangtze (“blue river”) is the largest river in all of Eurasia (5500 km). It originates from the Tibetan Plateau. In the upper reaches there is a mountain river, fed by glaciers and snow. In the middle and lower reaches it is a flat river, fed by rain (monsoon). In summer it floods. Abundant throughout the year. It is navigable; sea vessels can sail along it 120 km from the sea. Flows into the East China Sea. The Mekong also originates from the Tibetan Plateau, flows through the Indochina Peninsula and flows into the South China Sea. Nutrition and regimen are the same as the Yangtze.

18 slide

Description of the presentation by individual slides:

Yangtze River This is the longest and deepest river on the entire Eurasian continent. It ranks third in the world according to these parameters. The Yangtze flows through the territory of the People's Republic of China. River length: 6,300 km. This is the third longest river in the world. Where it flows: The Yangtze River originates in the Tibetan Plateau. The height of the source above sea level is 5,600 meters. From its source, the river flows for quite a long time side by side with another large river in Asia - the Mekong. In its upper reaches, the river makes its way through the Sino-Tibetan mountains.

Slide 19

Description of the presentation by individual slides:

In the Sino-Tibetan Mountains, the river quite often changes the direction of its flow and forms narrow, deep gorges. In its middle course, the river passes through the Sichuan Basin. After joining the major tributaries of the Jialing and Minjiang near Chongqing, the river flows through deep gorges known for their beauty and difficulty of navigation. Making its way even further, through the Wushan Mountains, the river forms the famous “Three Gorges”. The largest hydroelectric power station in the world was built here. In its lower reaches, the Yangtze passes through the Sichuan Basin and flows further along the southern part of the Great Chinese Plain. Here the Yangtze receives the waters of China's largest freshwater lake, Poyanghu.

Description of the presentation by individual slides:

Rivers of the Indian Ocean basin. The rivers (Indus and Ganges) originate in the Tibetan Plateau and the Himalayas. In addition to rain, they receive food from mountain glaciers that melt in summer. The Indus originates on the Tibetan Plateau. In summer, during monsoon rains and melting glaciers, it overflows widely, and in winter it becomes shallow and flows into the Arabian Sea. There are severe floods. The Ganges originates in the Himalayas. It has mixed glacial-rain feeding and during floods the river level rises by an average of 10-12 m. The Ganges is one of the most abundant rivers on the globe.

Indus River The Indus River is the cradle of India. This is one of the major rivers in South Asia. The source of the river is in the Himalayas in China, on the northern slope of Mount Garing-boche (Kailas Range). Kailash himself is also very interesting place. The Indus, like the Ganges, is one of the main rivers of the Vedic Semirechye. It is into it, according to the Vedas, that the heavenly sages descend from heaven. From its source the river flows under the name Sindhu and receives the name Indus after the confluence of the Ghar-Dzangbo tributary. In India, after a long mountainous section, the river enters a valley, where on its banks stands ancient city Leh is the capital of Ladakh.

Slide 23

Description of the presentation by individual slides:

After China, the river flows through northwestern India and Pakistan. At its mouth, the Indus forms a large delta. This is one of the largest deltas in the world. Its area is about 41,000 sq. km. Every year after the flood, the delta changes its appearance. Even the main channel of the river often changes. River length: 3,180 km. The river is fed mainly by glaciers, and is also fed by monsoons.

Slide no. 2

Description of the presentation by individual slides:

About 40 thousand km of precipitation falls on the surface of Eurasia, 23.5 thousand km of this amount is spent on evaporation. The annual flow from the territory of Eurasia together with the islands is more than 16 thousand km, i.e. slightly less than half of the total flow of all rivers on Earth. In terms of runoff layer, this is equal to 300 mm, i.e. above the average for the entire Earth as a whole. In terms of average thickness of the runoff layer, Eurasia is surpassed only by South America. However, these average values ​​do not completely reflect the characteristics of the distribution of internal waters within the continent.

Slide no. 3

Description of the presentation by individual slides:

Significant differences in structure and topography, climatic contrasts and the associated unevenness of precipitation and differences in evaporation create large differences in the distribution of both surface and groundwater within the mainland. Maximum runoff amounts (more than 1500 mm) are typical for the subequatorial and equatorial belts, especially for the islands of the Sunda archipelago, for the west of Indochina and Hindustan, and for the central part of the Himalayas. In other zones, such high amounts of runoff are typical only for a few areas of the Japanese Islands, the Alps and the Scandinavian Highlands.

Slide no. 4

Description of the presentation by individual slides:

Large areas in these same regions have an annual flow of less than 1500, but more than 600 mm. In most of Europe, Northern and East Asia annual flow ranges from 200 to 600 mm per year. The relatively small spaces of the Iberian Peninsula, the Danube Plains, the middle part of the East European Plain and other areas are characterized by a flow of less than 200 mm, i.e. a little less average size for the entire landmass. Huge territories of the Middle and Central Asia, the Lower Indus Basin, the Iranian Plateau and the Arabian Peninsula have a runoff value of less than 50 mm per year, and in many areas the thickness of the layer does not exceed 15 mm. These figures to some extent reflect differences in the density and nature of the surface water network various parts mainland.

Slide no. 5

Description of the presentation by individual slides:

Rivers of Eurasia belong to the basins of the Atlantic, Arctic, Pacific and Indian Oceans. The interior and southwestern regions are almost devoid of surface water and have no flow to the ocean. The territory of internal drainage (including the Caspian Sea basin) accounts for more than 30% of the total area of ​​Eurasia.

Slide no. 6

Description of the presentation by individual slides:

The uneven distribution of water surfaces depends not only on modern natural conditions, but also on the development features of the continent. Obviously, to the powerful uplifts that led to the formation of the highest mountain ranges in the southern part of the continent, climatic conditions The interior parts of Eurasia, although they were more dry than the climates of its outskirts, were still not as arid as they are now. In this regard, in the Cenozoic, in the central part of the continent, there was a developed network of rivers and lakes, with flow to the north, east and south. Tectonic movements that had a greater scope in the marginal parts of the orogenic belt than in inland areas, led to the fact that these areas were protected from the influence of the oceans. The associated climate drying led to a decrease and disorganization of surface runoff and the formation of vast areas in the interior of the Eurasian continent (Iranian Plateau, Tibet, the plateau of China, Mongolia, etc.), practically devoid of surface runoff.

Slide no. 7

Description of the presentation by individual slides:

Characteristics of lakes in Eurasia Lakes in Eurasia are diverse in origin, size and water regime.1. glacial-tectonic; The basins of these lakes were formed by tectonic cracks of Neogene-Anthropogenic times and processed by glaciers, have irregular outlines and significant depths. (For example: Wenern, Wettern, Mälaren, Payanne, Saima, Inari). In more southern regions, within the Baltic lake chain, there are clusters of dammed moraine lakes.2. glacial lakes are especially characteristic of the Alps. The basins of the world-famous alpine lakes were formed in tectonic depressions at the end of the Neogene, and then were processed and deepened by powerful glaciers descending from the mountains.3. Karst lakes were formed as a result of leaching of limestone rocks. This type of lake is common on the Balkan Peninsula.4. dammed lakes5. floodplain lakes 6. volcanic lakes

Description of the presentation by individual slides:

Modern glaciation Eurasia Modern glaciation of Eurasia is associated, on the one hand, with the islands of the Arctic and Subarctic, on the other, with the highest and most abundantly irrigated mountain systems. The polar islands are characterized by cover-type glaciation and a low position of the snow line. On Spitsbergen it lies on average at an altitude of 300 m above sea level. Glaciation has the character of shields, from which powerful glacial tongues descend and break into the sea. A large center of glaciation is located on the island of Iceland, where the position of the lower border of the nival belt varies between 700 and 1000 m. All mountain ranges are covered with firn fields, from which glaciers extend, feeding numerous rivers.

Slide no. 9

Description of the presentation by individual slides:

Modern glaciation of Eurasia In the mountains, the height of the snow line increases from north to south and from the outskirts of the continent to the interior regions. Therefore, the major centers of modern glaciation are not only the highest mountain systems, like the Kunlun, Karakorum, Himalayas, Tien Shan, but also much less high, but abundantly moist mountains of the Atlantic regions. In the Scandinavian mountains, where the height of the snow line varies between 700 and 1900 m, there is significant glaciation. In the Alps, the snow line rises to a height of 2500-3200 m; this is the largest center of mountain glaciation in Europe with a valley type of glaciers, from which almost all significant rivers of Europe or their tributaries (Rhine, Rhone, Po, tributaries of the Danube) originate.

Slide no. 10

Description of the presentation by individual slides:

Modern glaciation of Eurasia Modern glaciation of the mountains of Asia, although significant, is still not as great as it could be, judging by their height. The most high mountains rise in the interior regions of the continent, characterized by a sharp continental climate and low precipitation amounts, so the snow line and the lower ends of the glaciers lie at high altitudes. The height of the snow boundary of the Karakorum and Kunlun is 5000-5500 m. The Himalayas are 4500-5000 m. The length of individual glaciers in the Karakorum reaches 60 km, the maximum length of the glaciers on the southern slope of the Himalayas is 26 km. In the Eastern Tien Shan, the height of the snow line is 3700 m and the length of the largest glacier is 40 km.
