Earth
 He is the only planet in the solar system where there is life. 3/2 of the water surface is covered. The outer surface of the mountains, is made of sand and clay. Mount ground level are necessary to maintain the balance. I saw the earth from space, so we'll see great signs of white color. This water-filled clouds are present in Earth's atmosphere. The past few years have helped reduce the number of clouds which have the effect of Earth's atmosphere. Our earth is only one moon. Land in the Northern Hemisphere than in the Southern Hemisphere are Australia and New Zealand. North Pole and South Pole of six months and six months of day is night. Twenty-four hours of the day and night cycle is. Earth's human population has exceeded six billion. And humans are constantly engaged in wars.

History

  Earth's history


Thanks to modern research scientist in the detailed knowledge about the past. Earth and the other planets of the solar system, solar nybyula, after the formation of the survivors was the object of dust and gases, from 4.57 billion years ago, came into being. In the molten state, but with the passage of time began to collect water in the Earth's atmosphere and its surface will cool a crust (crust) format was adopted. Shortly after the Moon was formed. Scientists believe that a body the size of Mars thya (Theia), which was a tenth of Earth's mass, Earth collided and crashed into the moon came into existence. Part of her body was merged with the ground, some were far apart in space, and some portion of the Earth's gravitational clipped the Moon was formed.
Gaseous emissions from molten material and volcanic processes on the early Earth's atmosphere came to appearance. The liquid form of water vapor cools and the oceans were formed. More water came to Earth from comets asteroid. A chemical reaction at high temperature (self replicating) molecule (molecule) was formed about 4 billion years ago, and about 50 million years after the Earth was the ancestor of all life.Photosynthesis following the evolution of life on Earth to the sun's energy to be able to use directly. Photosynthesis borne oxygen began to accumulate in the atmosphere and the oxygen in the upper part of Atmospheric Ozone (ozone) began to change. Small cells of algae in large cells in the development of complex cells audience (eukaryotes) is called. Single-cell organisms gradually lost its biggest cities, towns was growing interdependence in the cells and the cells grew more specific for different tasks. The evolution of multicellular organisms such organisms. The ozone in the Earth's upper atmosphere (ozone) gradually formed a security barrier around Earth and the sun's ultraviolet rays (ultra violet rays) reaching the earth from the earth view of life secured said. After that spread all the way to Earth.




    The Age
    Although scientists disagree about the age of the universe. But think about the age of the earth is five billion years ago today a sprawling cloud of gas and dust of gravityThe demolition was divided into tkrun sun was located in the center kept the most gas. The remaining gas from several gas shells became. This cloud of gas and dust, and it became thnda shells were also thndy. Became the star shells and other planets. One of them is the shell. Sun in the solar system, 99% of the substance is incorporated. Due to its abundance and density of matter in the heat and light. The remaining one per century, were all the planets of the solar system is part. As the shells were shrinking the solar system began to heat. Being more substance in the cause of this severe nuclear response smtaw started and began nuclear explosion, the worst nuclear explosions, the heat was intense. Heat generated in the earth under their asulunky. Heat the substance evaporates off part of the upper parts of the atmosphere due to rain and rain. For thousands of years it was pouring rain. In the beginning there was the rain drops reach the ground. In this way, but were re-evaporated. Krurn millions of years, but the ground was cool. Rocks were also cleaned of its land and sea also came into being. The geological periods that have passed since his short game is.
    Pre kymryn the Pre Cambrian Time
    The oldest rocks in the formation of planet Earth today, began nearly four billion 57 million years ago. Pre-Cambrian time period ranging from 57 million today covers a long period. This time is four billion years. It was the beginning of life on Earth in the past.

    The Lower Palaeozoic Era era of ancient lower mhjrhyat

    It starts before the 57 million to 39 million years. The total period of 18 million years is made. In this era of life countless evidence found in the rocks. BeforeAlmost two and a half billion years of life being recognized. But most have not mjhrat. This stage is divided into three sub-periods.

    (1) The Cambrian Period Cambrian period
    (2) The Ordovician Period ardud Shane days
    (3) The Silurian peroid sluryn time

    The Upper Palaeozic Era era of ancient life upper mjhr

    Pjas years away from 39 million to 22 million years ago have been. It covers a total of seventeen million, and it is divided into four sub-periods

    (1) dyunyn Devonian Peroid = This time period is five million years. The animal appeared in the first place of burning.

    (2) The Lower Carboniferous Peroid = lower carbon cycles The cycles lasted eight million years.

    (3) The Upper Carboniferous Peroid = lower carbon generation, coal came into being in these periods. 4. The Permian Peroid = permian periods prmhyt this time is four and a half million years.
    The Mesozoic Peroid ancient mjhr the middle of life

    Pjas years away from 22 million to 6 million years ago has been up. If it is extended to sixteen million and is divided into three sub-periods

    (1) Three fallow period The Triassic peroid = This time lasted four million years. They flourish in this era reptiles.

    (2) The Jurassic peroid = mountainous time period it lasted four million years. Diane put in the time and octopus creatures were on the rise.

    (3) The Cretacious peroid = chalk the time period it lasted six million years. Born in the chalk reservoir and the flowers on the plants first appeared.





    The Cenozic Era era of new life

    This time period ranging from six million years ago until recently spread. The current form of the earth. This period is known as the Lion of the animals and flowering plants. This covenant agreementOpinion is divided into two parts.
    (1) The Tertiary peroid third time
    (2) The Quarternary peroid fourth time
    These two days have been further divided into chronological periods.
    (1) The Tertiary peroid third time

    This time the six million pjas million years ago from the time period of up to twenty-five million years ago, is spread. Ie it covers a total length of more than six million years. It was once the mountain. This agreement came into being in the Himalayan mountains. It was almost the same shapes of the continents are today. But something was different. For example, East Asia and West Asia, across a sea route and Contemporary Arab and most of Iraq and Iran, and Pakistan and India were part of the bottom of the sea.
In this era from beginning to end Madagascar and Australia were in the form of islands. Your Asia and North America during the overland route to Alaska and Siberia was present. Many anua the tiger came around the neck of the animal forms. The continents of North and South continent animal animals retained more than one match. South America and Africa in the early period of the animals is to some extent the northern continents. The shape and size of the Mediterranean and the surplus had been steadily reduced. Himalayas, â pranyz between France and Spain, a mountain chain that stretches from the Baltic Sea to the Mediterranean, is spread á, the Alps and other mountain ranges appeared. Become rift valleys in Africa. In the last days of the American West, Central Asia and North and South Africa, also appeared in the desert. The lion is the geological changes and the distribution of animals and birds on the planet has contributed significantly to the spread. Evolution of plant life by changing the look of the place. However, the most important in the evolution of animal lion had to be clickable. Mid-life stage (mysuz tick the Mesozoic Peroid) exist in the small animal was a tiger. But most of them had disappeared with their contemporaries. Just bag the animal and the animal tiger escaped from the placenta. The third period is divided into five sub-periods.
                                                                                                              
    (1) The first time Palaeocene nearby
    (2) fjry nearby Eocene age
    (3) small nearby Oligocene period
    (4) At the time of closest Mioicene
    (5) over nearby Pliocene age
    The first time Palaeocene nearby

    This time is approximately six million years. The six million years ago, five million years. Information about the bad times of life are lower. Why such rocks are found at the far mhjrat bad animals are safe. However, Asia and South America and the United States have some evidence.The lion is the animal pytys are 35 major series. The total base of which survive today. At the time, developed a series rarely get a mark, the more ancient the ancient rodents such dayynusar they were flourishing.

    Fjry nearby Eocene age
    This is the time of year almost two million pjas million. Before the five million from three million years. The animal appeared on the hooves of the tiger. At this time LionAlthough officials do not get much more mhjrat. However, this time the Lions have had enough information about the animals.and the ability to pass on the trees swinging, and the ratio of the volume of the body and mind of the person who is closest.

 Humiliated nearby Oligocene period

       This is the time of year almost nine million, three million years ago, ranging from two million years ago. At this time the animals lions have enough mjhrat. The highlight of this eraFeature a wide grass field on planet Earth came into being. With their grass eating animals appeared. First, most of the evil forest animals that eat the leaves were eaten. Niche hoof animals were in the vast majority of the time. The most gigantic lion in the same period the animals exist in Central Asia. The experts called insomnia thrym recalls it was a long-necked stork Dino, whose feet tall from the shoulders up â á about fifteen feet vertically or five meters. Mjhrat fjry a number of apes found in the region of the fayum. Early ancestors of elephants with their bodies are found.

    At the time of closest Mioicene

    This period covers the period of a million years. Ranging from two million years ago, a million years. At that time the forest was part of Eurasia. Near the end of the period of time a land bridge between the Eurasian and African continents by monkeys and apes moved north. Included in these giant apes who later disappeared. Called drayupthy what is'. The giant apes of today's era is considered the ancestor of mansun. In today's world, there are four types psyche.

    1 chimpanzee aurngutan 2 3 4 gibbon ape

    It arose in the psyche of the RAM. The human race is the grandfather or grandfather.

    Pliocene times more nearby

    This time, more than five million years of 'life spans. Ie up to a million years ago. At that time, the planet was cold and dry climate in most areas. The species diversity in horses and Randy was born. At the same time the forest animals and their habitat as a place to select Step faced. For some animals were wild and some plains. At the same time, giant apes 'How drayutphy, even great, great alhykl psyche Gigantopithecus' appeared in the plains. Its weight was more than 150 pounds. At the same time, the father of the human race 'southern apes "(astrylutphy How) also came in appearance. South psyche the same time learning to make tools. The further development of tools to work the next time (the fourth time) the highest stage of evolution, the modern person.

    (2) The Quarternary peroid fourth time
    This time last half million years, ranging from contemporary covers. The two are part of.
    (1) The nearby Pleistocene era
    (2) Full nearby Holocene period
    (3) very close Pleistocene era
    This time last twenty-five million years ago (and near to some seventeen million years ago), beginning from ten thousand years (or eleven thousand years) .Then pointedly that spans the length of two millionNinety-four hundred years is spread.

    In this period the strong seasonal changes occurred repeatedly. Once again, most parts of the northern areas, especially in thick layers of snow chagyyn thick. The thickness of ten thousand feet (three meters
) Or even higher, and then again after the ice melted. During the same period, eight of ice freezing and melting periods indicated. More than ten thousand years ago the last ice melt end. Thus, this period is called an ice age. Which repeatedly thawed and frozen. The last snow in the geological life was making. The first was a seven million years ago. On the basis of this transformation severe weather aqsamyn many animals were extinct and many revolutionary step in the tremendous evolution and the evolution stage Qualitative changes in the period. At the same time modern humans emerged in its present form. The rise in the dawn of humanity. Ancient stone belongs to the same period of time. Almost! Twenty-five million years ago, starting from twelve thousand years ago is over. Three of the Stone Age are applied respectively.

    (1) lower the stone age
    (2) Medium ancient stone age
    (1) Upper age of the ancient stones.
    Full of 'Holocene period
    This time last ten thousand or spread over eleven thousand years. Before the start of the melting snow fell. Today, about fifteen thousand years ago, the ice started melting process that happened suddenly. Scientists think the Earth from the sun's radiation increases due to increased heat. Brfyn nearly eight thousand years ago, if a melting pot of the rivers were full CPCs, the rains were even more. In an era when a flood. In the living body has not changed in generations. Except that one of two things, a tremendous increase in the human population, the great lion who quickly disappeared.

    At the same time, was also a little ice age. In 1750 it was booming. The old great ice age during the relatively warmer than the icy tuudy had appeared on earth.
