Слайд 1

Слайд 2

In the west of Siberia is the largest river in Russia - the Ob. The length of the river is 3600 km. On its shores such countries as Russia, China and Kazakhstan are located. Oil, coal, gas, peat are extracted in the river basin. Many fish live in the mighty waters. The Russian Federation appreciates and is proud of its water resources.

Слайд 3

The river originates in Altai. It is formed by the rivers Biya and Katun, which unite in this place. In summer and autumn, you can see a striped jet of water in the Ob. The thing is that the rivers have a different color of water. The first is greenish, and the second is white.

Слайд 4

Ob had many names. Every tribe that has ever lived on its shores has given it a name. Here is a list of the most famous: Salya-yam, As, Eme, Kwai, Kuai. Today's name has three versions of origin: from the Iranian "ob", which means "water"; from the Russian "both", since it is formed by two rivers and, in fact, from the word "ob", which means "snow" from the Komi language.

Слайд 5

The Ob is the only river that does not flow from north to south, but vice versa - from south to north. It permeates all the natural zones of Russia: in the south it flows along semi-deserts, and in the north along the tundra.

Слайд 6

The Ob is asymmetric: one of its banks is gentle, and the other is steep and steep.

Слайд 7

The Ob River has a mighty left tributary - the Irtysh River.

Слайд 8

Further, the Ob River meets the Novosibirsk hydroelectric power station on its way. This dam blocked the river back in the 50s. The length of the Novosibirsk reservoir is 200 km, the maximum width reaches 22 km. The depth reaches 25 meters. Locals call this huge body of water the Ob Sea.

Слайд 9

As well as near other large rivers, people settled near the Ob since ancient times. In modern times, the city of Barnaul, the city of Kamen on the Ob, Surgut, Nefteyugansk, Nizhnevartovsk, Salekhard, which are important cities in the development of the country, are located here.

Слайд 10

Nowadays, the river has been sufficiently studied and mastered, but the taiga expanses still remain untouched by people. The main value for Russia received from the Ob River is a transport highway. It is difficult for people to create roads in these taiga places, and nature itself gave them an easy way to pass through the West Siberian area. The river enables people to move into the deepest regions of the Siberian expanses.
