IX. Homework.§ 15, k.k.
Eurasia - the only continent on Earth washed by four oceans. The continent is entirely located in the Northern Hemisphere. Some of the islands belonging to Eurasia are located in the Southern hemisphere, Most of continental Eurasia lies in the Eastern Hemisphere, the extreme western and eastern points of the continent are in the Western Hemisphere.
Physiographic location.Eurasia includes two parts of the world: Europe and Asia. The border line between Europe and Asia is drawn along the eastern slopes of the Ural Mountains, the Zhaiyk (Ural) River, the northwestern coast of the Caspian Sea, the Kuma-Manych depression, the eastern coast of the Black Sea, the southern coast of the Black Sea, the Bosporus Strait, the Sea of Marmara, the Dardanelles Strait, Aegean and Mediterranean seas.
The extreme point in the north of Eurasia is Cape Chelyuskin (77 ° 43 "N), the extreme point in the south is Cape Piai (1 ° 1 b" N), the distance between them is more than 8000 km.
The territory of the mainland, stretching from west to east, is also vast. The distance between the extreme point in the west - Cape Roka (9°34"W) and the extreme point in the east - Cape Dezhnev (169°40"W) is about 16,000 km. Due to such peculiarities of the geographical location, all climatic zones and natural zones characteristic of the Northern Hemisphere are found on the mainland.
History of exploration of the Eurasian continent.
The nature of Eurasia has been more fully explored than other continents. This is especially true for the most populated regions of Europe and Asia. In Eurasia, the most ancient civilizations of the Earth emerged and developed over thousands of years. The culture and science of Ancient India, China, Assyria and Babylon provided the beginnings of geographical knowledge for modern civilization. In Ancient Greece, Rome, and the countries of the Arab East, the main directions of geographical study of the “Ecumene” - the inhabited earth - were formed. European travel to India and China, penetration into Siberia and Central Asia, and searches for land and sea routes to southern countries provided the first information about the nature of the continent and the life of the peoples inhabiting it back in the Middle Ages. Numerous expeditions for scientific purposes in the XVIII-XX centuries. expanded and deepened the existing initial general ideas.
The travels of Marco Polo, Afanasy Nikitin, and Semyon Dezhnev are widely known. The inaccessible mountains and deserts of Central Asia, as well as the greatest highland of Tibet, were explored by a number of expeditions by P.P. Semenov-Tyan-Shansky, N.M. Przhevalsky, Sh. Ualikhanov and many others.
However, the territory of Eurasia has been studied unevenly. There are still inaccessible areas of the mainland that are waiting for their explorers - the interior regions of Arabia and Tibet, the Hindu Kush and Karakoram mountains, the central regions of the Indochina Peninsula and many islands of Indonesia.

1.The northernmost of all countries in the world is Reykjavik (Iceland).
2.The Malay Archipelago is the largest archipelago in the world. Includes Greater Sunda, Lesser Sunda, Moluccas, Philippine Islands and a number of small islands.
3.In the Mozambique Channel between Africa and Madagascar there is the island of Europa.
Questions and tasks
1.What parts of the world are part of the continent? What objects does the border pass through?
2. Determine the geographical location of the continent by completing the tasks in Table 11.
3.What is the uniqueness of the geographical location of Eurasia?
Working in a notebook
Based on the data provided in the table, identify the mainland researchers. During what period did discoveries and research take place? Fill in the blanks in the table.
Try to answer
Take an imaginary journey around Eurasia. Tell us about the objects you saw and crossed.
The article contains information about the seas and oceans that wash the shores of the most significant continent on the planet. Describes the features and specifics of the coastal areas of the continent. All the seas that are part of the oceans washing the shores of Eurasia are described in detail here.
Seas and oceans of Eurasia
The eastern shores of the mainland are washed by the Pacific Ocean.
Rice. 1. Pacific Ocean.
The Eurasian Pacific coast is distinguished by its extraordinary dissection and diversity of islands. The islands and peninsulas of Eurasia, in turn, isolate a system of interconnected marginal seas from the ocean: the Kamchatka Peninsula and the Kuril Islands separate the Sea of Okhotsk, the Japanese Islands and the Korean Peninsula delimit the mainland and the Sea of Japan.
Eurasia is the largest continent on our planet. It is washed by all oceans.
Rice. 2. Eurasia surrounded by oceanic waters.
The islands that make up the area of the mainland surround its territory in a semi-ring. The Eurasian islands and archipelagos are mostly located in eastern waters. In the northwestern region of the mainland there are large islands and island groups.
TOP 4 articleswho are reading along with this
The northern shores of Eurasia are washed by:
- East Siberian and Chukchi Sea;
- Norwegian and Barents Sea;
- White, Red and Laptev Sea.
The southern ends of the continent are dominated by the Mediterranean Sea and the seas of the Indian Ocean:
- Red;
- Arabian;
- Andaman;
- South China.
The eastern part of the continent is washed by the seas of the Pacific Ocean:
- Beringovo;
- Okhotsk;
- Japanese;
- East China.
The continental tip of the west belongs to the Atlantic Ocean. The North Sea rules here.
The part belonging to the outskirts of the Pacific Ocean has a complex coastline structure. The Western Pacific belt is characterized by difficult bottom topography.
The continent contains the deepest depression and the highest point on Earth.
Eurasia is separated from the rest of the planet's continents by straits and seas.
Seas of the Eurasian continent
There are a huge number of seas washing Eurasia.
The continent, washed by four oceans, is recognized as a supercontinent. The gigantic piece of land owes its impressive size to this title. The total land area is over 54 million square meters. km. In addition to the mainland itself, this number also includes the area of 15 peninsulas.
On the continental shelf, near the European coastal borders, lies the Bay of Biscay, as well as the Baltic, North and Irish seas.
Rice. 3. Bay of Biscay.
Gibraltar connects oceanic waters with the Mediterranean Sea, which includes several basins separated by islands and peninsulas. The Black and Azov Seas protrude deeper into the mainland, which, thanks to the Bosphorus, are subsequently combined with the Mediterranean Sea.
The Scandinavian Peninsula is located between the Norwegian and Barents seas. In the eastern regions of the mainland, chains of islands and peninsulas separate the seas from the Pacific Ocean. The Sea of Okhotsk is separated by the Kamchatka Peninsula and the Kuril Islands.
What have we learned?
We found out how many oceans wash the lands of the continent. We received information about why this territory of the Earth received the title of supercontinent. We found out how many peninsulas belong to the territory of the largest landmass. We found out how and how the mainland is separated from the others. We received information that the planet’s seas are connected to each other by a system of bays and straits. We learned that most of the mainland is located in the northern hemisphere.
