2. Distribution of water resources in Eurasia. River basins Distribution of water resources on the mainland. Due to significant climatic differences in Eurasia, the water of the dry land is very unevenly distributed on its territory. Their thickest network is observed on the ocean coasts. With the advance deep into the continent, the number of reservoirs decreases. But the level of water supply in […]...

Near the coast of the mainland there are large sea areas. In the Atlantic Ocean – the Northern, Norwegian, Baltic, Mediterranean, Black, Sea of ​​Azov. In the Arctic – Barents. Karskoe, […]...
4. Basic facts on the topic “Physiographic location, discovery, study and relief of Eurasia” The physiographic position of Eurasia is determined by its size, a large extent from west to east and from north to south. Eurasia lies in all climatic belts of the Earth. It is the only continent that is washed by the waters of all four oceans. The coastline of the continent is strongly dissected, there […]...
5. Minerals of South America The wealth and diversity of minerals in South America are due to the structure of the earth’s crust. Their origin and location is associated with tectonic structures, the activities of the internal and external forces of the Earth. In the folded areas and shields of the ancient platforms, mainly find ore minerals of igneous origin. […]...
6. Basic facts on the topic “Natural areas of Eurasia” The natural zones of Eurasia are replacing each other from north to south – from the arctic deserts to the moist equatorial forests, but not all of them are stretched by a continuous strip from west to east. This is due to the variety of climatic conditions and the features of the relief on the […]...
7. Climatic zones and regions of Eurasia The great extent of Eurasia from north to south determines the formation over its territory of all types of air masses of arctic, temperate, tropical, equatorial. Therefore, the continent is located in all climatic zones of the northern hemisphere. The considerable length of the continent from west to east predetermines the difference in the climate […]...

9. The influence of atmospheric circulation on the climate of Eurasia The climate of the continent is affected by the constant movement of air due to the formation of areas of high and low atmospheric pressure, especially the western transport – the constant wind of temperate latitudes. From the area of ​​high pressure over the Atlantic Ocean, it brings moist sea air to the continent. Marine […]...

11. The influence of man on nature in Eurasia Man by his economic activities greatly changed the nature of Eurasia, especially the zones of mixed and broad-leaved forests, forest-steppes and steppes. Here, instead of natural vegetation, agricultural lands appeared, cities were built, villages were built. Many of the wild animals, having lost their habitat, are on the verge of extinction. Plants and animals that […]...
12. The structure of the Earth’s crust of Eurasia The territory of Eurasia has been formed for hundreds of millions of years. The structure of the earth’s crust of Eurasia is more complex than that of other continents. Eurasia is located within three large lithospheric plates: the Eurasian, the Indo-Australian and the North American. At the heart of the lithospheric plates are several ancient […]...

14. Influence of the underlying surface on the climate of Eurasia The relief has a significant impact on the climate of the continent. The predominance of flat areas in the west of Eurasia contributes to the development of humid Atlantic air masses deep into the land. Their influence is felt even beyond the Ural Mountains, although considerably weakened. On the Eastern European Plain, cold Arctic air […]...

17. Interesting facts about “Eurasia” The first map, which depicted Europe, Asia and part of Africa, was made by the ancient Greek scientist Eratosthenes of Cyrene. She was very imperfect. The land occupied most of the map. The Bosphorus is the narrowest intercontinental strait in the world. Its width is 750-3700 m. The name means “bullish ford”. The Kerch Strait, […]...
18. Lakes of Eurasia In Eurasia there are many lakes. The largest in terms of area lakes in the world include Baikal, Balkhash and Ladoga. However, the unconditional world leader is the Caspian Lake, which because of its considerable size is even called the sea. In Eurasia, along with giant lakes, there are thousands of small ones that resemble […]...
19. The relief and minerals of South America 1. What processes form the relief of the east of the continent?

It was proved that Australia is a separate continent entirely in […]...
25. Forest steppes and steppes in Eurasia When moving deeper into the continent within the temperate zone, the amount of precipitation is gradually reduced. Wooded areas are becoming less and open spaces covered with thick grass are larger. So gradually the forest zone passes into the forest-steppe, and that, in turn, – into the steppe. Forest steppes and steppes occupy the interior […]...
26. Geological structure, minerals and climate of Oceania The geological structure of the islands of Oceania and their origin are closely related to the structure of the bottom of the Pacific Ocean. In the west of the Pacific, the Pacific and Indo-Australian plates converge, forming uplifts. In the places of their collision, earthquakes and volcanism are observed. Most of the islands of Oceania […]...
27. Taiga in Eurasia The natural zone of the taiga, or coniferous forests, occupies large areas in the north of the temperate zone. The summer here is quite warm, precipitation falls 300-600 mm. This is quite enough for the growth of trees. Since the zone of the taiga is full of permafrost, water can not infiltrate into the lower […]...
28. Inner waters of Eurasia 1. Why are large areas covered in Eurasia with modern glaciers? The northern islands and peninsulas of Eurasia, as well as the belt of high mountains in the south are covered with snow and ice, which do not melt throughout the year.

29. Subtropical forests and shrubs in Eurasia Subtropical forests and shrubs cover the natural zones of hard-leaved evergreen forests and shrubs in southern Europe and variable-moist forests in the east of Asia. The zone of hard-leaved evergreen forests and shrubs is common on the coast of the Mediterranean Sea. It’s a dry, hot summer and a rainy winter. Brown soil soils are […]...
30. Influence of geographical latitude on the climate of Eurasia The climate of Eurasia is very diverse. The north of the continent lies beyond the Arctic Circle, the southern parts – between the Southern Tropic and the equator. This determines the location of Eurasia in all thermal and climatic zones of the Earth. As in North America, with the progress from north to south, the […]...
31. Tundra in Eurasia To the south, towards the line of the Arctic Circle, in the conditions of the subarctic climate, the zone of the tundra – swamped treeless areas stretches. In Asia, the tundra extends far to the south. In Europe, because of the influence of warm currents, the area of ​​this natural zone is much smaller. The […]...
32. Natural areas of Eurasia 1. What is the law of natural zoning in the territory of Eurasia? This geographical law in the territory of Eurasia is most clearly manifested in the sequence of alternation of natural zones. One natural zone replaces another when moving from north to south. 2. It is known that in the forests more vegetative mass […]...
33. Mixed and deciduous forests in Eurasia The zone of mixed forests does not form a continuous band. It is located only in the west and east of the mainland.

36. Relation between the forms of the Earth relief and the structure of the lithosphere The lithosphere is the hard shell of the Earth, consisting of the earth’s crust and the upper layer of the mantle. Forty years ago, a scientific theory of lithospheric plates arose. According to this theory, the lithosphere is broken by giant cracks into separate blocks – lithospheric plates. The boundaries of the plates pass along […]...
