I Organizational moment

II 1) Vivchennya new material

To sound the song "The Volga River Leakage" at the Viconess Lyudmila Zikinoi.

(slide number 1)

What a song for? Who is the vison?

Are there little pictures of pisen, kazoks, prislivs about rychki, spring water?

Yak you guessed, let's talk about little things this year. The topic of our lesson is “Internal waters of Russia. Richki ". (slide number 1)

Christmas mi damo the back of the understand internal waters and it is possible to move from the head of the internal waters of our land - rik.

Water - one із which species resources Life is dumb without driving. Lyudin cannot live without water for 8 days. Itself 8 days may have been at the store of shackers, as they lead the way of mines, as they came to go to the exit in case of a collapse.

The government of the Lyudin sees good water. For stocks of good water, Russia is going to be deprived of Dania, oskilki until she befallen about. Greenland.

The main dzherela of good water is internal water, or land water. The stench of rіznomomanіtnі.

How do you know the inner waters? (slide number 2)

How are they like people? (rate, water supply, canals)

Internal water is tied with the components of nature. (Slide number 3)

The head components are to be injected onto the water, є relєf and climat. Yak tsі components are tied with internal waters, the rychok can be seen from the butt.

Russia is the land of numerical riks. Dovzhina rik varies in thousands of kilometers, S pool - in millions of kilometers. (slide number 4-9)

2) Reversal of the home staff (table-card "Richka Rossiya"

The owner of "Zakhovan" has the names of 21 riches of Russia. Vikreslyuyuchi without interruptions line (by name) according to 1 name, know the "captured" little ones, see them and know them in the atlas.

Who do you know about mustache rychki? Apparently їх on the card (board)

(Walk 3-4 scholars)

3) The rychki must be carried to the pool of 3 oceans and the inner dry area. Let's go over the table. (Slide number 10)

Most of the river flows into the Pivnichny Ice Ocean. Winning 65% of the territory of the country. Here you can find a river Lena, a small river, Anisei and a river with the largest pool beyond the area, Ob.

Why do the best little rivers flow to pivnich? (great territory of Russia maє uhil for pivnich)

To the pool The Pacific There is a great Amur river, like passing the border of the country, as well as the Anadir river.

Why are great riks at a gathering in Russia so rich, like at a party? (at the descent of the girski ridges, short rivers, skidnykh schiliv ridges)

There is a large Russian small river Volga, Terek, Ural until the dry region.

Don, Kuban, Neva lie to the Atlantic Ocean basin.

Otzhe, the relay is injected directly into the leak.

4) The skin okremo was taken in a unique manner. Ale the stench of all є the house of a part of the rychka. Guess the part of the little picture and the main understanding.

(slide number 11)

5) Backwardly from the profile of the river (slide number 12)

girski rivninni

Rivninnikh rik more. For what? (Most of Russia - rivninn)

Rivninna rychka maє wide valleys, quiet flow.

There are rapids and watersheds near the mountains. (Slide № 13-16) Smells of little use for ship navigation. Butt of one zhirskikh Terek. The yak axis will be described by M.Yu. Lermontov in his “Terek” wing:

Terek viє, wild and evil,

Mіzh skeletal masses,

Tempest crying yogo,

Sluzi to fly with breezes.

6) Relief is injected into 2 sizes: fall and uhil rychki.

Padinnya-tse rise between a loop and a hand in meters. (Slide number 17)

H = H1 - H2 de H1-absolute height of the loop

H2-absolute height of the girl

Richkas, which flow into the sea, may cause the height of the 0 m-code.

Whenever the rychka flows into the lake, the rim of the surface of the water flows into the lake by the height of the hand.

Yaksho rychka vitikє from the lake, rіven of the surface of the water є the height of the stream of the rychka.

Virіshennya of tasks for the purpose of assignment and success of the child.

# 1. Visibility of the fall of the Volga River (slide number 18)

Round ~ 300m (Valdaiska visochina)

Ustya (-28 m) (Caspian Sea)

# 2. Visitors to the date of the Angari rychka. (slide number 19)

Ustya - Фінська zatoka -0 m

The value of the drop in the injection is for the given characteristic:

Uhil-vіdnoshennya fall of the river (cm) to її dozhini (km)

Uhil padinnya dovzhina

(slide number 21)

Development of tasks:

№ 1. Visnachiti got the rychki of the Volga. (Slide number 22)

H = 328 = 32800 cm

I = 32800: 3531 = 9 cm / km

№ 2. Visnachiti got the Angari rychka. (Slide number 23)

Padіnnya = 380 m = 38000 cm

Dovzhina 1826 km

Uhil = 38000: 1826 = 20.8 cm / km

№ 3. Visnichiti got the Nevi river. (slide number 24)

H = 4m = 400cm

I = 400: 74 = 5.4 cm / km

Uhil the rychka injected the swiftness of the rychka flow. Chim is a big uhil, tim is more rapid.

Uhil rychki 12c. By designating the share of Bishop Ivan. The population of old Novgorod, not satisfied with the obscene behavior of Bishop John. Vyrishilo vignati from this place. Plit from Ioann was let down the Volkhov rivulets, taking a cob in the Ilmen lake, where it flows into Lake Ladozka. Novgorodians took the tse "miracle" yak "the banner of the Lord". I Bishop Ivan turned to his throne with honors.

It’s easy to explain. The surface of the surface appears, like the Volkhov stream, even smaller. If in the lower reaches of the Volkhov we see the boards, the water flows in the lower reaches, lower at the upper reaches, and the Volkhov flows at the zorotny straight. In ancient writings, the Volkhov River was called kalamutnaya.

And how do you know about the procrastination of the name іnshih richok? (revision of the home staff of the children)

Onisei - view of the old Kirgiz ENE-SAI - "MATI-RICHKA"

Cupid - "the little girl is great and strong"

Anadir - "strumok, scho against in the mountains" (named exactly as meaning, form, walking)

Angara - from the Evenky and Buryat words, which means "mouth, pasture". Richka on the cob is moving away from the pasture, so that the water from Lake Baikal is glazed without blame.

Ural - along the Ural mountains.

Kamchatka - on the eastern coast of Kamchatka.

So, for the name of the deyakie richok, you can make a mistake.

VI Homework. (Slide number 33)

Apply great rivers to the contour map

Pick up riddles, greetings, orders about rychki.

Vipisati y zoshit rychka - a record holder, vikoristovuchi handler and kart.

Nev a– rychka at the private entrance of the European territory of Russia, in the Leningrad region and the city of St. Petersburg

The name of the rychka is posed from the Sarmatian word "inflow", "sea", from the Finnish word - "swamp", "tryasovina", and from Swedish - "new river". The first riddles about the Neva date back to 1264 rubles. By the name of the won, she went to agreements between Novgorod and Nimetsky towns from 1269 r. Vodozbir small rivers in the borders of Russia (81.4%), Finland (18.5%) and Bilorusia (0.1% of the water intake area). The Russian part of the water intake is included at the border of seven sub'ekts of the Russian Federation. On the banks of the Neva Roztashovani Mista Shlisselburg, Kirovsk, Vidradne, St. Petersburg, village. Ust-Izhora and ін.

Neva viplya Ladozkoe lake and flows into the Nevskaya Bay of the Finnskoy outflow of the Baltic Sea. Dovzhina Richki 74 km. The area of ​​the vlasny water intake of the rychka is close to 5 yew. km2, z urahuvannyam the pool lakes zagalna area of ​​the water intake to become 281.6 yew. km2. The turn of the rіchka to be located near the Shlisselburg metro station. Behind the backyard area of ​​the Neva basin, there is the 1st place in the middle of St. Petersburg and the Leningrad region, 13th - near Russia.

Vvazhayut, rychka vinikla 3.5-4 yew. rock_v that through a ditch of ladozk waters near the Baltic. V hand grip to be bagatoreleukavna delta with an area of ​​83 km2.

Water intake of Nevi roztashovany at the boundaries of the Baltic Shield. Cross-breeding lodoviks form relєfu -. On the first day from the places of Viborg, Priozerska, Petrozavodsk, Ust-Vidlitsi there is a weakly overlapping rivnina with a hunchy relief, on the first day of the cordon there is a strongly oversized rivnina.

At the time of the territory of the sea, rice is characteristic of the surrounding latitudes. Rіchna sum of fallen to the door 755 mm. The number of days from a strong snow cover does not change 100. A hot month is linden (average temperature is + 18.0 ° С). Naykholodnish - luthium (average temperature -8.0 ° C). At the Neva's arm, there are three ancient rumba, which reach the speed of 50 m / s. They tied storm surges near the Nevsky Bay and the Neva delta. The penetration distance of wind surges at the river syaga is 45 km.

The density of the riverbed varies from 0.41 to 1.29 km / km 2. Most of the rivers on the water intake of the Neva - Volkhov , Vuoksa , Luwati , Svir... Near the Neva itself, there are only a few small rivers. Area occupied lakes to become 17% of the water intake area. The stench is 1350 km 3 of water. Nybilshi lakes Ladozke , Onezke , Ilmen(Russia), Saimaa (Finland). The coefficient of swampiness of the territory is expensive 13%. V Polystyvsky bog landscape(mіzhrіchchya rychok Lovatі, Polіsti ta Sheloni) Swampiness is maximum - 60-70%. On the water intake widened sod-pidzol and peat-boggy runt. Foxes occupy 55% of the water intake area, ornі land - 12%.

Neva protika in valleys the width should be 35-50 km (with a depth of 50-100 m). Zagalne padinnya channel Nevi is insignificant (close to 4.7 m), the middle pit becomes 0.064 ‰. Spiymannya that terasi on the day. The channel is vryzane, overly straight, stiyke. Take care of the steep, with small stripes, deposited with clayey lake-sea deposits. The middle height of the banks on the cob of the rivulet becomes 6-9 m, changes downward over the course of the rivulet. The width of the channel is 400-600 m. The average depth changes in the range from 7 to 11 m. mіskіy dіlyantsі rychki. The speed changes from 050 to 150 m / s. The channels of the presentation are represented by food runts; in zones with a shimmering pebble the bottom of a pebble, a boulder or a skelne.

Keeping an eye on the hydraulic camp of the Finskoy zatoka and the girl of the Nevi rested on the sleep of St. Petersburg (1703). Until 1892, the stinks were carried out at the same hydrographic posts... The middle stream of water near the Finsky zatotsi near the Kronstadt metro station for the warnings for the 1825-1939 rr. Accepted as the area is the value of the absolute value of all objects of the land of the country (zero of Kronstadt).

Water mode Nevi vіdrіznyа is weak vіrasnіst vіdrіznyа povin... At the warm period of time, there is an increase in water level (from 1.5 m on the cob and up to 0.10 m at the head) and vitrate water is tied from the reaction of Ladozkoye Lake to the spring tide to the new river water. It’s the go-to place to fix the birch tree - on the ear of the day. The maximum vitrate of water is 3400 m3 / s at the average, and 4590 m3 / s at the highest (for chervny or lime). The middle is minimal vitrate up to 1540 m3 / s, and the namensha vimiryan is 540 m3 / s (for example, winter).

Sheds (birch-grass) pass 24.8%, waterway - 30.5%, autumn - 27.1%, narrowway - 17.6% of river flow. At 27 km from the Nevskaya Guba there is a middle mountain vitrati vodi Nevi to become 2490 m 3 / s ( drain 78.587 km3 / pik). It changes from 1340 m3 / s (low water) to 3670 m3 / s (low water). The middle ball to the runoff is 278 mm, which is suitable for the runoff module 8.8 l / (s ∙ km 2).

On the river Nevi, from the ear to the Ivan's rapids, the water regime of the rivulet must lie down from the hydro-logical camp of the lake. From the hand to the Ivanivskiye thresholds of growth into the inflow of the Finnish inflow (at the period of the period of annihilation of the growths and surges). Nagin at the ear Nevi beckon the superfluous one on the cob, and nagin on the cob - the beckon on the ear. In the minds of major surges of the water surface in watercourses delta moved by 161-300 cm and more, which led to poven... Become a victor at the Nevi delta when the water rises up 160 cm above the zero of the Kronstadt foot stock. In case of catastrophic drafts, the growth of perevishchu is 300 cm (1777, 1824, 1924). For the seizure of St. Petersburg from the deadly povens near the Nevsky Gubernia was completed (2011) save up(Dovzhina 25.4 km). The stench of zdatnі zapobіgati poveni with pіdyom rіvnya vodi at 530 cm from the zero of the Kronstadt foot stock.

Turbidity The volume of the Nevi is relatively small (the average is 6.1 g / m 3). The middle vitrate is suspended by the load on the Nevi door, 15.3 kg / s. At the Nevskaya lip, the average one is 0.622 million tons of sediment.

Mineralization of nevskoy water changes from 30 (attachment) to 70 mg / l (charge). In the middle of the day mineral speech in rychkovy water become 38 mg / l. Medium-grade vitrate for the distribution of salts up to 95.4 kg / s. Shchorichno Neva to wine up to the Finskoy inflow 3.01 million tons of salt. Nevska water is admitted to the hydrocarbonate class and calcium group. The water is even more soft (the hardness is absorbed from 0.4–0.8 mg * eq / l). On the cob of rychka, the water can reach 90-100%. Water quality on the cob of Nevita in the Ladozkoe lake we are cleansing the waters (born in 2005). The city of St. Petersburg, the nevska water, has become obstructed, and the boundaries of the place are obstructed by the waters. For Nevskoy Guba characteristic є eutrofuvannya water mass.

The average water temperature in the Neva during the open channel becomes + 9.5 ° С. The average temperature of river water in lime trees is close to + 18 ° С. At freezing little pictures can be shaped sunk from p_dvischennyam rivnya vodi up to 4 m. The stench is set on the Ivan's rapids as a result of the ryasny’s ​​setting on the inner-water ice. At the hand of the rychka, the ice rises earlier, lower on the cob (at the middle, 5 and 21 breasts are evident). The best ice on the ice to become 45-50 cm, in the boundaries of the place 35-45 cm. The Neva freezes for 2-5 months. Nevi is characterized by a form of two lodokhodіv, scho z'єdnuOnezke Lake from the White Sea. Popular river cruises, the participants of which may be able to pave the number of monuments of nature, architecture, bridges and embankments of St. Petersburg. Neva is a floating water object for rafting and fishing (ide, chub, lalin, lash, roach, blue and blue).

- Yak wee good luck, let's talk about little girls this year. The topic of our lesson is Internal water of Russia. Richki "( Dodatok 1 , SLIDE) Christmas ladies in the background of the inner waters and the head of the inner waters of our land - rik.
- Water is one of the most important types of resources. Life is dumb without driving. Lyudin cannot live without water for 8 days. Itself 8 days may have been at the store of shackers, as they lead the way of mines, as they came to go to the exit in case of a collapse.
- At the state priesthood of lyudin, I will drink water as a head rank. For the reserves of good water, Russia will sacrifice the deprivation of Dania, which must be left to Fr. Greenland.

- The main dzherela of good water is internal water, or land. The stench of rіznomomanіtnі.
- Do you know how much you see the inner waters? (Let us show you SLIDE)
- How many people do they have? (Set, waterways, canals)

- Internal water is tied with the components of nature. ( Dodatok 1 , SLIDE)
- Head components, which can be injected onto water, є relєf and climat. Yak tsі components are tied with internal waters, the rychok can be seen from the butt.
- Russia is the land of numerical richok. Dovzhina rik is surrounded by thousands of kilometers, the area of ​​the pool - by millions of square kilometers.
- All rivers are carried to the basin of the three oceans and the inner spaceless area. ( Dodatok 1 , SLIDE).
- Most of the river flows into the Pivnichny Ice Ocean. Winning 65% of the territory of the country. There is a small river Lena, a small river Anisei and a small river with the largest pool beyond the area - Ob.
- Why do the best little rivers flow pivnich? (Great territory of Russia maє uhil for pivnich)
- To the basin of the Pacific Ocean there is a great Amur river, which passes through the cordon of the country, as well as the Anadir river.
- Why are the great richokers not so rich at the gathering of Russia, as at the pivnos? (On the Uzbek coast of the Pacific Ocean, there are ridges, short rivulets, and there are some small ridges.)
- There is a large Russian rychka Volga, Terek, and the Urals until the dry region. Don, Kuban, Neva lie to the Atlantic Ocean basin.
- Otzhe, fuel injection direct flow.
- Skin okremo was taken in a unique manner. Ale in them є bedroom - the whole part of the river. ( Dodatok 1 , SLIDE)
- Zgadaimo part of the little river. (the teacher on the slide shows the element of the river, and the boys call it: smut channel, dzherelo, girlo, tide)

– There are 2 types of rivers that fall in the profile of the river:. (Dodatok 1 , SLIDE)

- Rivninnikh rik more. For what? (Most of the territory of Russia - rivninn)
- Rivninna rychka maє wide valleys, calm flow. Girski rychki may vuzki valleys and boisterous currents. There are rapids and watersheds near the mountains. ( Dodatok 1 , SLIDE) The smell is not enough for ship navigation.
- The butt of one z girskih rychok є rychka Terek. The yak axis will be described at my own head Terek M. Yu. Lermontov.

"Terek viє, wild and evil,
Mіzh skeletal masses,
Tempest crying yogo,
Slyzi to fly with brizes. "

– Relief is injected into two sizes: fall and catch of the river.

PADINNYA- The price difference between the coil and the hand in meters. Dodatok 1 , SLIDE)

H = H 1 - H 2 de
H 1 - absolute height of the coil
H2 is the absolute height of the girl.

- Richkas, which flow into the sea, droop the height of the 0m arm. Whenever the rychka flows into the lake, the rim of the surface of the water flows into the lake by the height of the hand. Yaksho rychka vitikє from the lake, rіven of the surface of the water є the height of the stream of the rychka.

Uhil = 32800: 3531 = 9.3 cm / km

Visnachiti got out of Nevi.
Padinnya = 4 m = 400 cm
Dovzhina = 74 km
Uhil = 400: 74 = 5.4 cm / km

Viznachiti got the rychki Deer.
Падіння = 930 m = 93 000 cm
Dovzhina little girls = 4400
Uhil = 93000: 4400 = 21.1 cm / km

- Uhil the rychka injected the swiftness of the rychka current. Chim is a big uhil, tim is a big swiftness of a little baby.

- Richka stole from the XII century. by designating the share of Bishop Ivan. (Read urivok from the literature)
In one of the Novgorodian literatures, a tsikava podia is described, which was introduced in the 12th century. The population of old-time Novgorod, lacking in the obscene behavior of Bishop Ioann, was violated by the name of this place. They let the Volkhov rivulets go downstream from Ioann, yak beckoning a cob in Lake Ilmen, and flowing into Lake Ladozka. Ale plit was carried at the zorotny bik, in the lake Ilmen, so the rychka flowed in the opposite direction. Novgorodians took the tse "miracle" as "the banner of the Lord", and Bishop Ioann with honors turned to his throne.
It’s easy to explain. The surface of the surface appears, like the Volkhov's counterpart, is even rather small. If in the lower reaches of the Volkhov we see the boards, the water flows in the lower reaches, lower at the upper reaches, and the Volkhov flows at the zorotny straight.

- And now, I'll fix it with atlases and contour maps.

IV. Bagato poets assigned their virshi little children. (Hloptsi in k / k write a letter, and the reader will read virsh)

Mikola Yakushev about the Volga: (SLIDE)

Not dim, not wide,
Throughout the Valdai Territory
Ledve sensitively jiggle a stream,
Through the stones of the path, vibrating.
That is the win of the coastal pisok,
That is rapt in the bushes of lossє,
I do not know a little bit,
On a new check in advanceє.
How many miles you need to go,
Kryz yak pereshkodi break through,
A little bit of a rykok with him illumination at the road,
Slippers of seagulls spin over him.
Skіlki of old mine rockіv,
Skіls hvil rose in stakes,
Skіls rise to great places
Over the steep banks.

Molchanov-Sibirsky about Angara:(SLIDE)

Pidstupna, dashing, impelled,
My dear daughter to Baikal - old,

Mighty Siberian Richka.

O. Ponomarenko about about:

Obrodna - yak shche warmer
Will I tell you about you at the Virshahs?
B'єshya ty krіz swamps, krіz taiga,
Vlіtku - all blischa, charge bіlіuchi,
Hard ice has that in dim frequent snig.
Nobles, they did not call the goddess
Mi you - more than once your deprivation
With kindness, we, hanty, we saw.
I reread the riches of the sh hardly chi
Ti, you take care of your bosom.
Leave the water ringing in the spring,
Ty pidnimash barges, motor ships,
Flesh crumbles like islands.
Mista, settlements and backwaters
On your own for pivnich tyagnesti.

A. Sofronov about Don: (SLIDE)

Stars Don take a cob,
De prikhovanie vіchny strumіn,
Down the river bed is great
Where in the distant lands?
From a simple birch
Don bere ear;
З-під grass of Moscow earth,
Ivana - lakes on the shore.

Leonid Popov about Olena:(SLIDE)

You, beauty - a little girl,
Zhіnoche denouncing,
Navigate your name

We will caress you not for nothing
Baptized with the word
Uninvolved, scho was born
Ty is in the land of the suvorom.

M. Yu. Lermontov about Terek:

Give up, about the old man - the sea,
Give me a trick of my khvili!
Having walked in the open space,
Look for an hour and a minute.
I was born at Kazbek,
Hmara breasts of indignation,
With someone else's possession of the people
Vichno clash boo ready.
I have fun with yours
Rosoriv old Dar'yal
І boulders їm for glory
The herd drove in a whole.
