DURING THE CLASSES

I. Organizing time(1 min.)

II. Repetition of the studied (5 min.)

- At the last lesson, we got acquainted with the climate of our mainland. Let's repeat.

- In what climatic zones is Eurasia located? (In all but equatorial)

- Where is the "pole of cold" of the Northern Hemisphere? (Oymyakon, in Yakutia)

Show on the map one of the wettest places on Earth. (Cherapunji, at the foot of the Himalayas)

- Determine the type of climate according to climatograms (slide 2) (Moderate, arctic, subequatorial)

III. Update (3 min.)

Announcement of the topic of the lesson and staging learning objectives in front of the students.

Teacher: We continue to study the largest continent of the planet - Eurasia, the continent on which we live. Let's do it today virtual journey along the internal waters of Eurasia and get acquainted with some of its rivers and lakes, find out their features.

- Guys, what types of inland waters do you know? (Rivers, swamps, lakes, groundwater, glaciers, reservoirs, ponds, permafrost)

Check answers on slide 3.

IV. Solving learning problems (25 min.)

Name the rivers of the Northern basin Arctic Ocean, Pacific, Indian, Atlantic, internal flow.

What do rivers depend on? (depending on relief and climate)

We go to the first region:

1 berth. "The Biggest Lake"

This lake-sea is the largest inland lake on our planet. Unlike the neighboring Black Sea, the Caspian is completely surrounded by land and has no outlet to any of the oceans. The surface of the water in it is 27 meters below sea level. Where the Volga meets the Caspian Sea, it divides into more than 800 channels and forms an amazingly fertile delta.

Viewing a fragment of the documentary film "The Kingdom of the Russian Bear" (slide 4) - 1 min. 45 sec.

2 pier. "Fast river"

- This is the second longest river in Europe after the Volga. It is born in the German Black Forest and flows east, cutting through Vienna, Bratislava, Budapest and Belgrade - four European capitals. At the end of the journey, this great river forms a delta in the territory of Ukraine and Romania, and flows into the Black Sea.

Despite their beauty, the rapids brought the river notoriety. The fact is that this is a relatively shallow river, but fast enough. The bottom is covered with rocks, which greatly complicates navigation, no matter how hard they try to clear it. In our time, ships can hardly climb the river, and until the middle of the 20th century, this was not possible at all, and ships had to be transported by trains. (Slide 5)

3 berth. "Ladoga"

The bowl of the lake was formed due to tectonic activity and glacier movement. The unique location of the lake allows you to observe the "white nights", as well as enjoy the enchanting view of the northern lights. The lake is surrounded by taiga forests and rocks. In the ancient sagas of Scandinavia, he was called Aldoga. It is the largest lake in Europe, and also the deepest: 233 meters. Interesting fact- 35 rivers and many small streams flow into the lake, and only one flows out - the Neva. Also in the lake there are three large bays - Volkhovsky, Svirsky and Shlisselburgsky. (Slide 6)

4 berth. "Russian hero"

The Yenisei is a unique natural formation in terms of geography. The mighty river runs almost strictly along the meridian and divides the territory of Russia approximately in half. (Slide 7)

5 berth. "Pearl of Siberia"

The student tells the legend: (slide 8)

“Father Baikal had 336 son-rivers and one daughter, Angara, they all flowed into her father in order to replenish his waters, but his daughter fell in love with the Yenisei River and decided to run away to him. Baikal, learning about this, tried to block her path by throwing a Shaman-stone to the source. But Angara ran on, then Baikal sent his nephew, Irkut, after her in pursuit, but he took pity on Angara and turned off the path. The Angara met the Yenisei and flowed further along with it.

6 berth. 长江 - "Long river"

This river is the third in the world in terms of full flow and length. And in Eurasia, it is the longest. The waters of the river are widely used for irrigation of rice fields, especially in the Sichuan basin. Floods often occur. This is China's main waterway. Four of the country's five major freshwater lakes drain into the Yangtze. The civilization of southern China appeared on its banks. The Yangtze River is home to two endangered species: the Chinese alligator and the Chinese paddlefish. (Slide 9)

7 berth. "Fresh - salty (Appendix 3)

A unique lake with different water. It is divided by a narrow strait into two parts - western and eastern. In the first - fresh water, in the second - brackish. Balkhash was known to the Chinese under the name "Si-Hai" - the Western Sea, the Turks and Mongols, who designated all geographical objects to the west of their settlements in white, called it "Ak-Dengiz" ("white sea"), and when the borders of their states moved to the west, the lake became "blue" (east). The Kazakhs called the lake "Tengiz", which means "sea". This drainless semi-fresh water lake is located in the southeastern part of Kazakhstan. Balkhash is the second largest non-drying salt lake (after the Caspian Sea) and the 14th in the list of the largest lakes in the world, while the lake significantly changes its area according to the seasons of moisture: from 22 to 17 thousand km2. (Slide 10)

8 berth. "Soul of India"

In art, the Ganges is depicted as a sensual and beautiful woman, carrying an overflowing jug in her hand, which symbolizes the richness of life. Often she is depicted sitting on her Makar - an animal with the body of a crocodile and the tail of a fish.

The Ganges is often referred to as one of the dirtiest rivers in the world. Its waters threaten the health of about 500 million people living in the river basin and its delta. Already starting from the upper reaches, the Ganges becomes very dirty due to runoff, which dumps the population and numerous industrial enterprises. Another reason for the pollution of the channel is the overpopulation of cities along the river: during floods, the Ganges collects a large number of human impurities.

The Ganges is a popular burial site. Since the river in Hinduism is the link between Earth and Heaven, it is believed that when people throw the ashes of their dead relatives into the waters of this river, they help them get to heaven. Therefore, cremation anywhere along the river is desirable for Hindus. Often people bring the dead here across the country, and bonfires are constantly burning on the banks of the river, on which the dead are burned. Some companies offer transportation of ashes even from abroad and perform ash-scattering ceremonies over the Ganges. The poorest Indians simply throw the bodies of the dead into the water. Also an important ritual on the Ganges is Arti - the offering to the gods of lit lamps made of leaves, with a wick dipped in ghee. It is believed that the longer the lamp is lit, the more likely it is that the request that the Hindu asks the gods for will be fulfilled, while songs are sung. (slide 11)
