About 4.6 billion years ago our solar system was formed which includes the Sun, planets, their satellites and many more. Maximum part of Earth’s matter came from the stars and supernova around 7 billion years ago. It is believed that earth was formed around 4.4 to 4.6 billion years ago, it is a rough data it is only assumed not exactly proved. Since its formation earth have undergone a numerous changes catastrophically i.e., heat and gravitationally, environmentally, physically. The emergence of life on earth much later played a significant role in shaping the earth.
In the last few thousand years earth has witness a tremendous change in its climate which has changed the total scenario of the Earth and in the past few hundred years this change is tremendous due to human deeds like overpopulation, deforestation, industrialization, polution, water polution, air polution, unsystemetic constructions, industrial gasses, nuclear tests, space travel, missile test, chemical test, bio tests etc. these deeds have triggered the natural methods of resisting changes like the increased frequency of earthquakes, volcanoes eruption, flood, drought, global warmin, climate disbalanced, iceberg melting, drinking water shortage, ozon layes damage, shortage of fresh air etc. Earth is a stable system, which maintains its stability by its deeds, human tries to challenge the nature, which in returns results in resists changes and brings disaster to the mankind.
It is assumed that in about 15 billion years the formation of sun like stars and our Earth like planets will be rare and long time before that sun would have burned our Earth and life on it will come to and end.
The gravitational collapse of the clouds of hydrogen and higher metals during star formation, the non-hydrogen elements can be found in the middle and outer surface of the rotating disk like supernova. The changes (unhomogenities) in hydrogen clouds leads to the formation of the planets and non-hydrogen matter serves as wells which increased the size of these clouds which results in planets formation. The slamming of the high velocity and low velocity matter also helped in smaller clumps which again collided to form bigger mass.
There is another theory that cosmic dust together formed particles, particles clumped together to form gravel, gravel formed tiny balls, tiny ball formed big balls, big balls formed tiny planets and finally became the size of today’s planets. As the size of the clumps increased the number of collisions between the meteorites and satellites decreased. So only few items were available for the planet formation so it took a large time for planet formation. A calculation is suggested that it would take 100 million years for an object with a diameter of 10 kilometers to reach the size of earth’s diameter.
After a few million year from the star birth’s time the tiny particles revolving around it coagulates into larger bodies and finally into full blown planets. After a few 100 million years the debris crashes and clumps into the planets or is thrown out of the solar system. Thus leaving the solar system clean just likes ours. Some forms of life present in today’s earth is around 1 to 1.6 billion years old.
The pre-earth grew by increase until the temperature of the inner layer of the protoplanet was sufficient to melt the heavy metals. These heavy metals with heavy mass sink to the center of the earth and formed the mantle of the earth.
This formed iron core catastrophe, which results in the formation of layered structure, which resulted in formation of earth’s magnetic field. This happened only 10 million years after the beginning of the earth’s formation.
During the planet formation the huge cloud of silica must have surround the earth and condensed afterwards to form the rocks and mountains. The earlier lighter elements from the solar nebula like hydrogen & helium must have escaped from the earth’s atmosphere due to earth’s heat and solar wind. All this happened when earth has been formed around 40% radius of its present radii. And due to gravitational pull an atmosphere was formed around earth, which included water.
Origin of World Map
Setting up the boundaries for living and traveling had been an important part of life 7,000 years ago. The map was important helping object for masses around the world.
Till date it has become a necessary tool for govt. offices, Army, Airlines, Navy, travelers and for all activities where location needed. Started from cave paintings to computer’s digital Images, one cannot deny the role of world map.
History of World Map, First World Map or History of World. The world was hidden for several years from the eyes of cartographers, in early years people were using lines, symbols and shapes to locate an area, time changed and people have developed geographical knowledge and developed a map.
