The seas are like great natural complexes. Synopsis for the lesson "seas yak great natural complexes"

Azov Sea to lay down to the pool Atlantic Ocean, Through the Kerch canal, go to Chornim

by the sea. Sea of ​​Azov is found in svit, yogo maximum glybin 14 meters, middle glybin close to 7.5 m. Area 37,000 km. The sea is rich in inflow and estuary. Most inflows:

Taganrozkiy, Temryukskiy, Kazantipskiy, Arabatsku, Obіtochna, Berdyanskiy. On call Arabatska strelka vidokremlyuє from the sea inlet Sivash (Rotten Sea), the yogh coast is covered with a ball of salt.

The gently sloping and low bank of the tortoiseshell. The mows were set only on the winter Uzbek coast, the result of the trivial robots of the sea khvil, which weighed the seashore. There is a great number of kis - characteristic particularity shores of the Azov Sea.

Temperature regime The Azov Sea is characterized by a great seasonal minivist. minimum temperature the charge is determined (very much), the water is cooled down to +3 ... -3 0С. Repairing the chest of the Azov Sea, the sea froze. Vlіtku + 24 ... + 26 ° С.

The main plane is the circular current of the shores of the Sea of ​​Azov against the godinnikovo line. The average fluidity of the leakage becomes 10-20 cm / s.

The salinity of the sea is three times less, lower average salinity in oceans and warehouses 12 ‰. The maximum salinity of the waters is observed in the Sivash - 250 ‰. Minimal indicators of salinity on the first night of the sea, in Taganrozkiy zatotsi. The salinity indicator is constantly changing for the change in the flow of the fresh waters of the river. By the sea

carry their own waters of the river Don, Kuban, Mius, Kalmius, Berda, Obitochna.

per biological productivity Azov sea loan perche mice v light. The versatility and the richness of the life of the Sea of ​​Azov will be explained together organic speeches, Yake is 5-6 times more, lower in other waters. Richki will supply the sea with a multitude of inorganic and organic speech, as they wander from the ground.

inorganic speeches necessary for development roslinniy svitu, Organіchnі - for creatures.

Among the messengers of the Azov Sea, there were most of them found, like in the other seas, they were already. Until the їkh number

There are two species of molluscs, one of the species of cancer-like and most of the worms. 115 species of ribs have been registered in the Sea of ​​Azov. Krym sea sturgeon, lash, pike perch, ram, chekhon, mullet, oseledtsya, hamsi, flounder, scourge, fish and freshwater ribs: crucian carp, piskar, roach, lin, pike. From the Seredland and Black Sea, there are tuna, mackerel, vugor, which are responsible for permanent migration. The Azov blue dolphin, the sea pig, and the Chornomorsk dolphin are found here.

Azov water Volodya dominating authorities. Mala glibina dry water progr_vannyu. Admission of the seafood and water, sun, beaches with a golden sip, so you can develop

recreational resources... On the territory of the Donetsk region there are populations: Melekino, Yalta, Urzuf, Novoazovsk, Sedovo, and other resorts.

Sea of ​​Azov є important transport highway... The main port of Donetsk region is Mariupol.

problems:

Throughout the XX century, practically all the rivers that flow into the Sea of ​​Azov, bully barricaded rowing for the stem of waterways. Tse called up to a significant speed skidannya nice waters and mule in the sea... pislya

the opening of the hydraulic unit on the Don, the salinity of the sea has begun to move... Zvyazu z zim lost their minds and spawn rib.

the main dzherelami zabrudnen є promislovі enterprises.

The transparency of the waters of the Azov Sea is low. Vlіtku, as a result of the boisterous development in the upper balls of water and found in the growing and living organisms, the water is filled with a bright green barn. Tse appearances are called " flowers "sea.

Internal subject to the link: the topic "Geographic location of Russia" and "The seas that wash the shores of Russia".

PLAN-CONSPECT

I. Organizational moment.

teacher:

This year's lesson is not easy for us:
Vidkritiy, svyatkovy and zavodny.
I ask you for a little more
I want you to succeed at the level.

II. Vivchennya new material.

Actualization of knowledge.

  • Give a viznachennya PTC understand? (PTK - Natural - Territorial Complex - it is natural to add interconnected components of nature on the first territory).
  • Reinvent the components of the PTC. ( klimat, girski breed, live organisms, internal water, etc.).
  • Yak of vzamopov'yazanі components in PTK? (Exchange of speech and energy).
  • Point the butt of the PTK? (Geographic shell, seas, natural zones, Fascia, etc.).
  • About what PTC id Mova (riddle)?
    There is water all around, but there’s a pittyam bida. (Sea)
  • Yak Wee think, yak is the topic of our lesson? (Seas, like a great PTK). (slide 1).

teacher: Years at the urotsi we will rise in price on the seas of Russia and the bishop will teach the lesson the coming up.

Russia is a sea power.
Vona in stormy vіtri
Svіy sail of linen trimal
Until the days of Peter.
P.S. Komarov

  • Why is Russia called a sea power? (Russia has a great number of seas).
  • How about the sea in the territory of Russia? (12 seas of the Holy Ocean and the Caspian Sea, which are carried to the inner drainless basin).
  • Name and show the sea on the map. (A robot with a map atlas and maps on the screen). (slide 2).
  • What will the seas be like for the main indicators (temperature, salinity, glybin, organic light)? (Rіznimi).

teacher: Throughout the lesson, we will see the problem "What is the territory of Russia for the development of the minds of the natural minds of the sea."

(The teacher is stripped of the tsili and the lesson) ( slide 3).

teacher: Hello, you will rise in price for two seas of Beloe and Azov, and until you think about it. ( slide 4).

  • Why are you going to the road? (On older ships).

teacher: Let's go to the old ship (learn to roam the boats from the paper and give it a name. The robot can be played with a musical suprovid).

T. K. seodnі mi doslіdzhuєmo the versatility of the natural minds of two seas, that is, when a boat in a white colora is a prelude to the natural mind of the White Sea, and a blakit colora is in the Azov Sea.

  • What settlements are we converting to the road along the Bilom and the Azov Sea? (Robot with maps to atlas). ( slide 4).

teacher: In the course of the journey to the end of the sea, we will store the mandarin tree, and the table itself in the tree.

1. Peculiarities of the nature of the White and Azov Seas (tabulation of tables; the robot with maps to the atlas, the text of the handler and additional literature; solution of problem food in the view of Heuristic chaos, madness with the elements of explanation).

Features of the nature of the White and Azov Seas (slides 5 - 15)

Right for the eyes
9. Environmental problems. Change in species versatility, vinification of seals, enrichment with naphtha products and important metals. Change in species versatility, increase in salinity, enrichment with naphtha products and goodies.

The situation is problematic.

Teacher: The salinity of the waters of the Svitovoy ocean is to be deposited as the leading rank in the period of atmospheric fall and vaporization, as it changes in the fallow in the geographic latitude. It is possible to catch up with a set of regularities, but salinity in the White Sea is to blame but lower, lower in the Sea of ​​Azov. We found that salinity is lower in the Sea of ​​Azov, lower in the White Sea. What is the cause of this manifestation?

  • Yak bureaucrats pour on salinity? (A little bit of a rychok falls, geographic latitude, Vaporization, etc.)
  • And is the width of the channel between the suspended seas and the saltiness? (So).
  • Consider the width of the channel between the Bilim and the Barents Seas. (The duct is wide).
  • Take the width of the channel between the Azov and Black seas. (Vuzky channel).
  • You can make a whiff of it. (In the Azov Sea through the Vuzky Kerch canal, it is less brackish waters from the Black Sea, and in the Bila Sea through the wide channel Gorlo from the Barents Sea more saline waters rise. T.O. the salinity of the sea is also infused with the width of the channel between the continental seas.)

Writing tables to learn how to change patterns.

teacher: Increase the amount of children who have been trained in the course of the preliminaries of natural minds. Who has the characteristics of the sea? (Slide 16).

a) Figures of specificities: internal seas, coastal lines are heavily porous, and some ecological problems.

b) rice visibility: area, clay, salinity, temperature, biological resources.

2. The reasons for the versatility of the sea (besid).

  • What is more rice for needs or benefits? (Acknowledgments).
  • Who is the cause of the two seas of Russia? (The issue of the problem is put on the ear to the lesson)
  • Why does Russia wash the seas of developmental minds behind natural minds?

On the versatility of natural minds, the sea is infused with such factors. (Slide 17).

  • geographic location;
  • climatic mind;
  • History of the campaign and development of the sea;

III. Closing the grafting material. (Slide 18).

a) Select one correct display and letter of correct display by inserting into the matrix. (The maximum rating is "5")

1. Mistseva is the name of the inflow of the White Sea.

B) the gate.

2. Biluha bagє in;

O) Black Sea;

P) Sea of ​​Azov;

P) White sea.

C) Azovske.

4. Pike perch, yorge sackє in:

O) the Sea of ​​Azov;

P) White sea.

b) Cards. (Dodatkovі zavdannya for quiet, hto fit with the first zavdannya).


Reflexion. Clap your thoughts about the lesson behind the help figur.


Vi. Home zavdannya... (Slide 19).

a) Paragraph 22. Suggestions for nutrition in the end of the paragraph.

b) Sleep on the onset of food.

The White Sea has an industrial type of water growth - lamina tsukrova. To what kind of inheritance is overwhelmed by the type of water in humans?

V. Leading the lesson і Displaying marks for the robot at the level.

The sea of ​​Azov is slightly softened,
More than a sea of ​​trochas - trochas pochornilo,
I don’t see it
Bilim call yogo or nasty?
Ale chi not an hour to turn to order
We do not need soft-boiled geography.

Mi vivchili salinity, resources,
Glibini vimіrya, were on the exact course,
All necessary facts were recorded in the schodennik
They put together the visnovka, the statute was approved.
Bully cross over to our way,
Ale was amicably able to bypass me,
Aje so tsikavo books to read
I am rich in new design.
