THE REAL HISTORY OF EARTH,DEVELOPMENT,CHANGES,COMPOSITION,EVOLUTION, EXPLOSIONS

How old is our Earth?

Scientists believe that our Earth was formed approximately 4.54 billion years ago. About 14 billion years ago, there was a massive explosion, which the scientists later named The 'Big Bang'. It relalised radiation, particles and huge clouds of atoms, dust and gas. Our Earth is believed to have been born as a result of this Big Bang.


Where in Space our Earth located?

Our Earth is located in a spiral galaxy named the 'Milki Way' which is  part of the solar system also consists of the Sun,the Moon,the other seven planets and their moons,numeeious comets,astroids andminor planets. The Solar System was formed from a large,rotating cloud of interstellar dust and gas called the 'Solar Nebula',orbiting the milki way's galactic centre. The Solar Nebula was composed of hydrogen and helium,created shortly after the Big Bang.


How did the Earth form?

After the Big Bang, particles were floating around in space. The force of gravity pulled the particles together and they began to spin around a centre. Some of matter squeezed into a tiny fireball,which grew bigger and bigger,untill it gave birth to the Sun. The rest of the molecules kept spinning in a cloud of dust that was left over from the formation of the Sun. In time, a few molecules clumped together. Then, the clumps began to crash into each other and stick together to make bigger clumps. Finally, there were huge clusters of metal and rock, hundreds of mile across, good enough to be called planets. One such cluster is our planet Earth. Its formation was largely completed over 10-20 million year.

Earth evolution,just-born earth look like

What did the just-born Earth look like? The jist-born Earth was like a blurred patch of blistering rock and choking fumes. However, space was cold, so the Earth also began to cool down. Approximately, 3,000 million years ago, the planet was cool enough for land masses to form. The centre of the planet was mainly melted iron. As time passed, the surface cooled to form the crust, which was mainly silica and the system condensed into water How did the Earth start or iting the Sun? The Sun's gravity caught the Earth, as well as the other planet,and pulled them into orbit around the sun. On one hand, the Earth's momentum was always trying to carry it always from the Sun's in a straight line. On the other hand, the Sun's gravity kept pulling the Earth toward the Sun. As a result, because of the centrifugal force, the Earth ended up orbiting the Sun in an elliptical path. How far is the earth from the sun? The Earth is the third planet from the Sun. It is situated at average d...

CAUSES OF COLD WAR

 What are the causes of cold war ? Ans: The causes of cold war are as follow:- 1. Orthodox view : The orthodox view was that cold war was essentially a result of view.Agressive policies of Soviet Union and stalin which needed to be confronted.The expansion of soviet union threatend the national security of the US. 2. Revisionist view : According to the revisionists, the foreign policies of US were especially desined for the promotion of capitalism,globally.Thus,accordingly them,the US policies and its quest for promotion of global capitalism has created insecurity for the Soviet Union. 3. Post-revisionist view : From this perspective,the cold war was not so much the responsibility of either side,but rather the results of predictable tensions between two word powers that had been suspicious of one another for nearly a country.
