The world

The third largest planet , according to the distance from the Sun , is the world's fifth largest planet in eight solar systems. It is one of the four solid planets in the Solar System . The world's other name is " World " or "Nilgah". The Greek name known as "Earth", known in English as Gaia (Γαῖα) [n 5] , is the Latin name of the planet " Terra " .

The world is home to millions of species of people, including humans . The world is the only cosmic place where the existence of life is expressed. The world was formed 454 billion years ago. Within a billion years, life on earth came out. Earth's biosphere has brought significant changes in the atmosphere and other inorganic conditions of this planet . This resulted in the increase of the aerobic organisms on the one hand, on the other hand the level of weight was formed. These weight levels together with the Earth's magnetic field harmful solar radiation Stimulated the path of life on the planet's chest by expanding it. Earth's natural resources and its geological history and orbits have helped in the survival of life in this age. It is believed that the more than 50 billion years of life the earth will be able to survive.

The surface of the Earth is divided into several hard strings . These are called crustaceous patches . For billions of years, they have been deposited on the earth's surface. About 71% of the world's surface is covered by the ocean of saline water. Remnants have been formed on the continents and countless islands. There are also numerous ocean lakes and other water sources in the area. These are formed in the world's waterways . Liquid water is essential for life on this planet somewhere in the earth's crust counterbalance condition is not available. Earth's perennially covered ice ( Antarctic ice sheets ) or sea ​​ice ( Arctic ice cap ) is covered.Earth's interior is always functional. This has formed part of a relatively stiff Mantell thick layer, a liquid ex-center (which constitutes a magnetic field), and a solid iron -center consists of.

Earth has relationships with other objects in the universe. This planet has special relation with the sun and the Moon . At present, the Earth is orbiting its Sun in roughly 365.26 solar days [n 6] or one star in its orbit. The earth has 23.4 degree corners on its axis. As a result of the tropical year (36524 solar day) in this period rtuparibartana occur in the world. The only visible natural satellite in the world is the moon. 4.35 billion years ago the moon started circling the earth. Because of the motion of the Moon, the tidal wave of the earth is the resultAnd the slope of the earth's chamber is stagnant. The speed of the Moon gradually decreases the speed of the Earth. Between 3.8 billion and 4.1 billion years, there was significant change in planetary environment in the aftermath of the next monstrous earthquake with multiple asteroids .

The planet's mineral resources and organic resources are both essential for the survival of mankind. Residents of this planet are living around 200 independent sovereign states divided the entire planet. There is mutual diplomatic, tourism, commercial and military relations between these countries. Born of different concepts about human culture planet These concepts include the idea of ​​the world as a god, imagination of the flat world , and the imagination of the earth as the center of the universe . Apart from this, modern trends of visualizing the world as a composite environment are also noticed. This concept is now predominant.
