History of the earth as a planet presentation. Presentation of the earth, її development of the planet
Presentation on the topic: "Our planet EARTH is beautiful"
The presentation was prepared by Dubovska S.M.
Teacher MBOU m.Kerchі RK "School No. 23"
Our planet Earth is beautiful! Seas, oceans, foxes and fields, Wind and fog, boards and snow: Earthling skin is dear to you! Quiet is our planet - the Earth. Everything here is for comfort, everything here is for life. The planet was embellished by the people of pracі, zbuduvavshi roads, gardens, places. Oh, how the planet Earth is defenseless, In front of them, who has power in the world of our fools, Piervati and destroy the planet ready - Our sleep, loves, united breath. The earth is our ark, our fatherland, budinok, for whom we all live together with you. Let's do good and create the Earth, like a mother, and take care, and love! Lyubov Panasyuk
At the Earth Day in different countries for the tradition of sounding the Call to the World
In Russia, the action “Dialing the World on Earth Day” has been held since 1998 with the initiative and under the patronage of the pilot-cosmonaut of the USSR, Hero of the Radyansk Union A.N.
The beauty of the nature of our Earth was inspired in their creations by the poets of Russia
Enchanting Winter,
Enchantments, flis cost-
I under the snow fringe,
Unruly, dumb,
Wonderful lives of wines to shine. F. Tyutchev
It’s already snowing, bіzhat strings, At the vіkno the curtains blew. The nightingales will whistle soon, and the leaves will be clothed! Oleksiy Pleshcheev
- Oh, leto red! I love you bi
- If it weren’t for baking, she drank, that mosquitoes, that flies.
- You, all the spiritual vibes of the buffoons,
- You torture us; like fields we suffer from drought.
- Є in autumn first
- Short, but it's a miracle time -
- All day to stand like a crystal,
- I promenisti evening...
- F. Tyutchev
Nature is rich in its gifts and miracles.
Walking through the marvelous, kazkovy forest of our Planet
Kovbasne tree (kigelia)
Growth in tropical Africa. The tree took its name from the cowbass for its fruits, similar to cowbass, with a length of up to 60 cm, which hang from the bushes.
Fresh fruits of rubbish. For curing, dry, lubricate and ferment. Africans rejoice in the fruits of rheumatism, snake bites.
bread tree
Ridne for the western islands of the sea. It grows up to approximately 20-26 meters of the crown. Bring up to 200 fruits per season for friendly minds.
Dairy chi cow'yache tree
The fatherland of the tree is Central and Pivdenna America, it is also cultivated in Asia. It grows up to 30 meters of curl. The fruits of the tree are not natural, but milky sik is brown and savory.
Zuckerkove tree (beef licorice)
Shitty licorice lives in the forests of tropical America. The sound is already similar to a linden, with a great number of flowers, rich in nectar.
Salne tree
Cover with a ball of refractory fat similar to whisk. From the pour on the oil, they take off the oil, which is victorious in the production of candles and that sweetness.
paper tree
Paper tree (fatsiya paperova) growth in China. From usіh yogo parts it is possible to work high-yield papyr.
Milne tree (Sapindus)
In America and Asia, the fruits of the roslin - "mile peas" zastosovuvalis like a natural miyuchy zasib with pranny fabrics and clothes. In this hour, roslin is zastosovuetsya in cosmetics and like an ecologically safe and mild zasib.

Earth Day is held in order to make people respectful to the trendy and inconsistent middle ground on planet Earth
Let's embellish the Earth at once, Plant garden, plant flowers everywhere. Let's honor the Earth at once and put it down, like a marvel!
We forget that we have only one - unique, vulnerable, alive. Beautiful: hot summer, hot winter ... We have one, one such!
"Navkolishniy svit", 4th grade.
Meta teacher: set the task of designating the shape of the Earth, organize the robot in groups to develop hypotheses about the shape of the Earth, organize the discussion of hypotheses and model re-verification, reading texts and the residual nutrition of the shape of the Earth, looking at the globe from the look of the “model of the Earth” completely.
Helpers in children: globe, flat stake, cube, great ball, boat (can be folded from paper). The teacher does not show everything, but takes away the necessary moment.
ICT at the lesson: Presentation "Shape of the Earth".
Lesson Hide:
Slide 1: What is the shape of the Earth?
- Before us, people thought that the Earth was flat or bulging (like an old-fashioned shield) colo, as if it were standing on a support.
- Schodo pіdpirok among different peoples were different thoughts.
Revision of homework (advancement of children): it was necessary for the students to know the material from that, like the ancient form of the Earth of different peoples.
The teacher adds, as if it is such a need.
Slide 3: Statement about the shape of the Earth in Russia
In Russia, for the old hours, you could almost feel the same way. The drunken lad asked:
Didusyu, tell me, on what does the Earth stand?
- On whales, child, - old povіv. - On the great whales! And how do these whales collapse - the earth is shaking ...
- And why are the whales, didusyu?
- On the water, child!
- A water on what, didusyu?
- On Earth, child!
- What about the Earth?
- What a ti beztyamny! Adzhe tobi said that the Earth is on whales!
Such a Rozmova could continue without a break.
Slide 4: How the shape of the Earth was revealed by the Hindus
The ancient Hindus respected that the earth’s pіvkul was trimmed by chotiri elephants, and the elephants stood on a majestic turtle. But the stench did not care about food: and why should the turtle stand?
Slide 5: Statement about the shape of the Earth by ancient Greeks
At the early stages of the ancient Greek civilization, the thought arose that the Earth is a flat disk, oozing by the sea, every night the stars come out, the stinks of the stench will again zanuryuyuyutsya in the abyss. Helios - the Greek god Sontsya - rises into the sky on a golden chariot today.
Slide 6
U: On p.38 of the first helper to know, read how the Babylonians showed the Earth.
The text of the assistant: “The inhabitants of Old Babylonia represented the Earth like a mountain, sharpened by the sea. The sky spirals hard on the sea. Under the Earth - no day, hell for dead souls. At night the Sun passes through the hell, and in the daytime the sky.
Slide 7: Mandrivnik has mercy on crystal skies
Raising the price of the sea, our ancestors began to remember that, pushing up to the shore, you can hit the tops of the mountain, then the heights, and only then the low shores. And, on the other hand, for a posterigen from the shore, it was given that the windows were far away, and only sweat - the lower part of the ship. These warnings led the old ones to the thought that the Earth may have swelled its shape. Hello Yaku?
Slide 8: Awesome.
- It is not marvelous that people have long respected the flat Earth, like a roof on the table;
- It is marvelous that the human mind is still able to recognize the correct form of the Earth.
- Truth is, for whom a lot of thousands of thousands of years were needed. Helped people far away dearly.
Slide 9: Ferdinand Magellan (1470-1521) Portuguese navigator
Slide 10: Magellan's meta expedition
Lay the westward path to the Moluccas Islands - the right fatherland of spices, ahead of the Portuguese.
Slide 11: Ships of Magellan's flotilla (from an engraving on the cob of the 17th century)
On spring 20, 1519, a squadron of five small ships (San Antonio, Concepción, Victoria, Santiago, Trinidad) sailed from the Spanish harbor of Seville. 265 sailors and officers violated the roads. In the Spanish squadron, the Portuguese Admiral Ferdinand Magellan. Magellan putting his own vazhka goal: Vіdkriti way from the Atlantic Ocean to the Great
- to the Canary Islands
- far away for a day - to the islands of Green Misu,
- and then we’ll go on a pivdenniy stop.
- 29 leaf fall ships reached Brazil. Passage across the Atlantic without special needs, even though the flotilla was revisited by storms.
- The ships of Magellan destroyed the coast for a day.
- On September 10, 1520, the fate of the stench rose to the mouth of the river La Plati.
Magellan's expedition is not small about the distant way of any information.
Between the two largest oceans of the world, the mainland of America lies like a blanket. Before Magellan, those other seafarers tried to sail near the new unknown ocean, but for 20 years they inevitably came upon the shores of America. And the thought was formed that it was impossible to sail from the Atlantic Ocean near Velika Pivdenny. Magellan saw that through the land of America there were channels that crossed two oceans.

Slide 13: Ways of Magellan's expedition on the map of the world
How did you find a passage near the Pacific Ocean? Two of the Magellanic ships were washed up by a storm to the shores of Pivdenny America. The team immediately remembered the narrow gorge. That buv that passed, like a stench joked. Now the wine is called the Magellanic duct.
Having perished Magellan on April 27, 1521, on the Philippine Islands at the hollow core with tubes, without completing his life.
Slide 14: Ship "Victoria"
Less than 18 people and 1 ship "Victoria" turned to Spain to the harbor of Seville on 6 April 1522. Here were the first people, who made the round-the-world more expensive, as if it were three years without twelve days.
Spanish merchants were left satisfied. Brought 26 tons of spices more than paid for the costs of the expedition and the number of five ships.
It’s true, few people turned around, but they didn’t know about the merchants: people didn’t waste any kopecks on them!
Slide 15: The significance of Magellan's expedition
The significance of Magellan's expedition is important to reevaluate:
- After 20 rokіv poshukіv bula, nareshti, vіdkrit duct, later named after Magellan.
- It was up to Magellan herself to bring to the end on the right, like consecrating life to Christopher Columbus, - to pave the way back at the edge of the Skhod.
- The practical result is more expensive than the surroundings: the difficulties of swimming were not paid off by these benefits, as they could bring.
- The nature of this geographic significance was majestic. On the way, Magellan for good has put an end to super-girls about the shape of our planet, in practice, dovіvshi її kuljastіst.
- The establishment of the great Pacific Ocean called for the idea of a pure overriding of land over the sea, like Christopher Columbus spreading it.
Before Columbus, Europeans did not know about the foundation of the majestic continent of America; before Magellan, the stench did not guess about the right seas. And clean up America and the Pacific Ocean. Chi is great Earth to be deprived of? Such a її і was respected to the miraculously dearer than Columbus and Magellan. To the road, Magellan thought that the Moluccas Islands could not be farther away, 3000 - 4000 km, looking forward to the modern world. But really, the road was close to 18 thousand kilometers!
From that hour a lot of fates passed. Skіlki? (2007 - 1522 = ?)
slide 16: route
Slide 17: The Way of Magellan and Drake
Slide 18: Get directions.
The way of learning is shown on the slide by a felt-tip pen.
The slide can be twisted to show "your own" on the road (stored in groups), as well as to repeat the previously covered material.
D.Z.: Prepare information about the Trival (previous state) of the sea is more expensive.
If you are ready to richly remind, you can dedicate a lesson to him.
Slide 19: Photo of the Earth from the Apollo 17 spacecraft
Slide 20: Model of the Earth
Modern proof of the Earth's cult.
Food is discussed with the scientists: what can be done with these proofs for the hour of Magellan's voyage. Why?

LIGHTING THE PLANET. Near the young Sonts, a disk-like gas-saw haze was formed from the dawn speech, which was lost after the people of our luminary. In the dark, for a fluctuation of the forces of gravity from the particles of the saw, clumps settled down, as if united in a small body - the winter planet. The rest stuck together one by one, and sometimes they stuck together. As a result, a sprinkling of great bodies - proplanets - settled down, one of which was the EARTH.

EARTH ATMOSPHERE. A BRIEF HISTORY OF THE ATMOSPHERE. A BRIEF HISTORY OF THE ATMOSPHERE. In the first million years of the earth's hearts, the atmosphere was even more chilled in the ninth. The head of the won was a sum of nitrogen, carbon dioxide and water vapor. At the early stage of the formation of the Earth, volcanoes continuously blew carbon dioxide, which, like carpet, warmed the young planet. If the atmosphere stabilized, the first organisms vibrated, the buildings vibrated with sour. In the first million years of the earth's hearts, the atmosphere was even more chilled in the ninth.

At the early stage of the formation of the Earth, volcanoes continuously blew carbon dioxide, which, like carpet, warmed the young planet. If the atmosphere stabilized, the first organisms vibrated, the buildings vibrated with sour. By stretching the rest of the billions of rocks, the concentration of sour is left with a steady one.
HYDROSPHERES OF THE EARTH. Over 70% of the earth's surface is covered with water. Of these, close to 2% falls on a piece of ice, and fresh water and water vapor become 1%. On top of the Earth 4 billion years ago, the flooring was hot, so that water could not stay in a rare state. Close to 3.8 billion years ago, the Earth went cold, and soon the atmosphere of volcanic gases and water vapor settled down. Then the water vapor began to condense in a thunderstorm. Innumerable evils have fallen upon the Earth, which have covered the destruction on the surface of the planet. So the oceans settled down. After the setting of the oceans on land, the boards continued to fall, like they mimicked the salts from the rocks that carried them into the ocean. Axis why sea water is salty. The average won to take 35% of mineral salts.
CONTINENTAL DRIFT. This process is called convection. The shifting of the rocks of the mantle, the continental and oceanic plates, which lie higher, drift freely on the surface of the Earth. The solid surface of the Earth is made up of majestic plates of oceanic and continental crust. During the flow of heat from the core of the planet, mantles are generated, heated up, rise to the surface and fall down.
Month. Month. Holy Month. If the Earth has settled down, її a meteorite has fallen with the world of Mars. When hitting into space, the tricks of the earthly material were thrown, for which, it is possible, and the Month has become. Moon - the closest to the Earth is the heavenly body. Promin the light from the surface to reach the Earth with a stretch of three more than one second. A month is smaller than the Earth in size and mass. The monthly radius is 1738 km, and the Earth's is 6400 km. Masa Mіsyatsya 81 times less, lower on the Earth. All objects on the Moon are 6 times lighter, lower on our planet.
ORIGINAL LIFE. The first billion years of this our planet was inanimate. If life has arisen, it is unavoidable, but for that boule you will need water, acid and other speech. In the wake of chemical reactions, folding molecules are created, creating their own similar ones. Such molecules could be brought from space, or they could be synthesized from the simplest molecules of the Earth under the influx of lightning electric discharges and sleepy light. The simplest one-celled organisms, which lingered in the oceans, step by step hid themselves from the molecules that self-create. The most recent records of life skam'yanіlі surpluses of bacteria and algae, which is close to 3.5 billion years. Starting from the simplest organisms, life developed directly from rich people.

D DD The two main branches of the rosette are green creatures.
The first people One sacredly believe in the forefathers of mankind - Adam and Eve. A person to walk like a mavpi (according to Darwin) - they are similar to others. The first people were Sumerians, the third ones are hardened. Sumerians Sumerians Stars of stench came and boday until the race lay, until it was impossible. At Mezhirichchya Tigris and Euphrates at Pivdenny Mesopotamia 4000 years before the birth of Christ “black heads” appeared. Settling at Dvorichchi, the Sumerians started riti canals, brought water to irrigation, organized irrigation statehood, and established ship navigation. The lands blossomed. Places were built, temples with flat dachas, without veins, were obov'yazkovo. The walls were embellished with reliefs carved on stone with stories of the life of the Sumerians. These are your own assistants in stone.
To learn this year at the 21st century, the assistants at the stone could be boldly seen already on paper: volumes of pharmaceuticals and phytotherapy, collections of appendices and orders, encyclopedias of chemistry, astronomy and mathematics. The Sumerians won a folding system of calculation, which was based on a combination of numbers 6 and 10. In the world, they began to win so much recently, with the advent of computers.

Clinopis of the Sumerians. Clinopis of the Sumerians. The oldest known writing system is Sumerian writing, which far away developed into cuneiform, with which signs were seen with a stick (stylus) on tablets made of gray clay. A sprat of thousands of clay tablets, written off in cuneiform writing, has been lost.

Sleepy system among known Sumerians. For a long time in the past, they were hoarding the knowledge of the ancient Sumerians in the future Sonyach system, showing only two other inaccuracies: they called Pluto a companion, and they said that between Mars and Jupiter, the planet Nibiru (“Peresikaє”) wraps around. And recently, astronomers found out: Pluto is not a planet, but between Mars and Jupiter, if the orbit of the great planet passed, it seemed that great tricks were lost. The Sumerians themselves believed that the Anunaki came from the very planet Nibir. The Motherland was hit by an environmental problem: the atmosphere became more and more thin and the inhabitants were threatened with death in case of accidents.
Although the Sumerians were endowed with an unseen intellect and blamed everything that could be found, they did not linger on the Earth for a long time. In the old days of that mysterious civilization, the world was left with nothing more than wits, and drank in rich clay tablets.
Planet Earth On planet Earth, people are guests, They are allowed to live. Milyardi lie on the tsvintar, It is not given to them by immortal buti. Ale, you need to stay quietly, calmly, to love the Lord the Earth, And we have constant wars, We try to divide the Earth. Catastrophes on our Earth: Hurricanes, quakes, tsunamis It seems - do not live with evil! Only good hi panuє mizh you! Try to be sensible to people, you will be happy together, people - Life will be happy and joyful, and your life will continue longer!

Our planet earth.
The Earth settled down for about 4.54 billion years to that disk-like mass of gas, the saw, which was lost in the adoption of the Sun, as it gave the ear of the Sonyachny system.
Volcanic degassing created the first atmosphere, but in this May there was no sourness and it would be toxic to people in that day-to-day life.
A large part of the Earth was melted through active volcanism and parts of the earth with other space objects.
One of such great zіtknen, as if to lie down, brought to the sickness of the earth's axis that molding of the Moon.
This year such cosmic bombardment stumbled, which allowed the planet to cool down and make a hard crust.
slide 3
Delivered to the planet by comets and asteroids, water condensed into gloomy oceans. The earth became, nareshti, a living room for life, and the early її forms enriched the atmosphere with sourness.
Accepting the first billion lives on the Earth came in small and microscopic forms. Close to 580 million years ago, the life of a richly rich life was folded, and before the Cambrian period, it experienced a process of rapid diversification in most of the main types.
Nearly six million years ago, the line of hominins was cremated, which gave rise to the appearance of chimpanzees (our closest relatives), and gave up to modern humans
slide 4
From the moment of molding on our planet, biological and geological changes are constantly being observed. Organisms develop without interruption, acquire new forms, or die near the end of the planet. The process of plate tectonics plays an important role in the formation of the oceans and continents of the Earth, as well as life, like giving stench a back. The biosphere, in its own right, has made a significant impact on the atmosphere of the other abiotic minds on the planet, such as the ozone ball, the expansion of the sour, and also the creation of the soil. If people do not want to accept the connection with their apparently short period of life, these changes continue and will be continued by the stretch of the coming billions of years.

Previously, there was only one continent on Earth, which was called Pangea.

)Earthruses - underground deposits and shaking of the surface of the Earth, vicking by natural causes (the main rank of tectonic processes), or (inodі) piece processes (vibuhi, filling of water reservoirs, collapse of underground empty ridges). Small parcels can also be called like a lava during volcanic eruptions.
Mostly on the whole Earth, there are close to a million earthworms, but most of them are so insignificant that the stench is overwhelmed with insignificance. Indeed, strong earthquakes, buildings viklikati great ruins, trapleyutsya on the planet about once every two days. Most of them fall to the bottom of the oceans, and this is accompanied by catastrophic consequences (as an earthworm can do without a tsunami under the ocean).
Earthquakes are the most visible behind these deserts, like the stench of buildings. Ruinuvannya budіvel that spores are called out by the colivans of the soil or giant tidal whirlpools (tsunami), which are blamed for seismic displacements on the seabed.
The international guardian of earthworkers registers to find the most important and insignificant of them.

Plate tectonics.
Slide 14
Plate tectonics is the main process, which is a significant world form of the Earth's appearance. The word "tectonics" is similar to the Greek word "tecton" - "budivelnik" or "teslyar", slabs of the lithosphere are called slabs in tectonics. According to the theory, the Earth's lithosphere is made up of gigantic plates, which give our planet a mosaic structure. On the surface of the earth, not continents collapse, but lithospheric plates. Plentifully shifting, the stench chomps on the continent and the ocean floor. Plates zіshtovhuyutsya one by one, seeing the earth's firmament at the sight of the mountain ranges and mountain systems, or they are pressed into the deep, creating overhead depressions in the ocean. These days of activity can be interrupted only by short catastrophic podia - earthtrucks and volcanic eruptions. Mayzhe all geological activity is surrounded by air between the plates. Those who move the slabs have been brought to a full extent (for the help of companions, you can change the difference between two points on different slabs and determine the speed of their movement), but the mechanisms of their movement are still up to the end of nevidomy. Using this theory, I will explain the rubble of the slabs, which are the mantles, which are blamed in the commodities, the hot zones are thrown up to the surface heated, the rotten speech - plumes, as if with their onslaught, the continents are stirred up.
slide 15
Between these plates are zones of maximum high seismic, volcanic and tectonic activity. So it’s self-imposed, it’s been established that they stoked “spitting” the bridles of these cordonies, one to one by appointment. The width of the skin slab is clearly visible, but the middle one is smooth, which is 4-5 centimeters on the river. Ruh slabs provoke surface earthquakes of different strengths, shards of rukh skin slabs are visible between the dry slabs. In some places, the slabs are also zishtovhuyut, forming new ridges on the surface. And in other depressions, the plates can overlap one by one, satisfying deep oceanic depressions. As soon as it appears, then the rock, on the slab, which zanuruetsya, undergoes melting and metamorphism. In some valleys, it simply spreads out in mantles, or it rises through the cracks of the lying slab, in a magmatic look, in such a rank, they blame the volcanic-active area in the coastal areas, and then we form the mountain lances. a wealth of things that are with the geology of the Earth. But I can’t say with confidence what is going on there, at the depth of over 70 kilometers.
- Planet Earth, basic information about the Earth as a planet
- The presentation was prepared by:
- students 11 "B" class
- Bakhteva Julia, Grushetska Olena
- We forget that the Earth is a cosmic body, a planet, and only those who are “blakitna” are firmly aware of the current information about the planet Earth. Below are the main stories about the Earth as a planet.
- The geometric shape of the Earth is a celestial wrapper, the numerical values of the radius are like this: equatorial 6378.169 km, polar 6356.777 km, average 6371.032
- The volume of the planet Earth becomes 1.083 trillion cubic kilometers.
- The average thickness of the Earth is healthy 5518 kg per cubic meter
- Planet Earth weighs 5.976 septillion kilograms (10 in 24 steps).
- Like a cosmic body, the planet Earth wraps around the Sun in an elliptical orbit, from an average velocity of 29.765 km / s, with an average distance between them of 149.6 million kilometers. The eccentricity of the orbit of the planet Earth is about 0.0167, so the trajectory of the orbit around the Sun is close to the stake.
- The width of the wrapping of the Earth is near its own axis 0.4651xcosα, de - tse geographic latitude. The center acceleration on the equator line is 0.033915 m/sec near the square. The acceleration of gravity on the Earth is 9.806665 m/s squared.
- The first cosmic speed, it is necessary to hit the body, so that it began to collapse in orbit around the Earth, reaching 7.9 km / s. In order for the body to overcome the earth's gravity and move away from our planet, it can collapse at a speed of no less than 11.2 km / s (another space one).
- Planet Earth has a total area of 510.2 million square kilometers, and 149.1 million square kilometers (29.2%) and 361.1 million square kilometers fall on land. (70.8%) to the seas and oceans. Moreover, the weight of the ocean is 1.45 sextillons (10 21 steps) kilograms.
- Middle altitude, like the continents of the planet Earth rise above the level of the sea, up to 860 meters. The average depth of the Light Ocean becomes 3700 meters.
- Zrozumіlo, remember all the digits no matter what, ale stink
- help to put together a blatant statement about space body,
- called "planet earth".
- Those that the Earth has a round (kulyastu) shape, know to inspire children of the preschool age. Tse vvazhaetsya experimentally confirmed by the fact. We began to finish the old Greece, and finish it successfully. Theoretical and experimental proofs of the mathematicians of the Pythagorean school are up to date and exact. One of them, Eratosthenes, was able to calculate the parameters of the stake of the Earth. After the first flight into space, the fact became obvious. It’s true, quiet, who believes in a flat Earth is not so small. Ale їm obviousness proof є.
- For the sake of justice, it is necessary to state that the shape of the earth cannot be taken in by a bushy one, it is spherical. The diameters of the sphere are due to but equal, on the basis of the diameter of the cooler. The spherical shape of the Earth is explained by the cosmological theory of creation. As far as the theory goes, the Earth has settled into a cluster that is made up of gases, a cosmic saw, and so on. The clot follows its own orbit, wrapping around the axis. The forces of gravity, which are settled during wrapping, small the speech at approximately the same distance, near the future center of the Earth. Axis i appeared as a spherical planet. The proof of the theory of the Earth's movement is a rare form of the earth's mantle.
- Even though it shows the homeland, it is placed at the camp of negligence. For the daytime, near the body with a great mass, the homeland fills up with the shape of a cool. Oskіlki our planet under a solid crust may have a core, then according to the same law, the Earth may have the same shape, only the shape of the other troch is flattened from the poles through the wrapping of the Earth, and in the equatorial region it is navpak, it is drawn by the rahunok of the forces of the central air
- These are the reasons why a round milny mіkhur is the optimal shape for rozpodіlu vnutrіshny and zvnіshny vice. The round shape of the Earth was laid down, if it was rare to get it out. In addition, add some wrapping around the hairy axis. How do you see kloduvi muhuyut kuli bachili? The stench wraps them up.
- Vіdpovіdno to the methodology described by F.M. Krasovsky (approximately the same as Isaac Newton), the Earth has the shape of an ellipsoid. And not just an ellipsoid, but a cardioidal (suggestive with the shape of the heart: it is twisted at the point of the Pivnichny pole and squeezed into the Pivdenny) trivisual (three values of the equatorial diameters) ellipsoid. And a round one can be less than a globe!
- Wanting to mentally vvazhayut the round Earth. The water is splashing from the poles all through the same wrapping - the water center force is signified. The qiu form is called ellipsoid. Ale and tse - those same intelligence. The shape of the Earth is folded - with depressions and ledges (the oceans do not burn on the edge, but the great exhalation of the Earth's surface about the theoretical form of the elіpsoida). So, for the formation of our Earth, we foretold an okremy term - "geoid"
