History of Earth!

History of the Earth starts from 4.578 billion years ago. The age of the Earth is near about 1/3rd of the age of the universe. In that time, an intense change occured on Earth.

At that time, Earth was formed by accretion from the solar nebula. However, Volcanic outgassing likely created the primordial atmosphere. It was actually a huge blast. After a long time, such cosmic bombardments ceased and then the Earth cooled down. Water that was brought here by comets and asteroids condensed into clouds and the oceans took shape. Moreover, geographic and biological changes are still occurring since its formation. Many organisms came into being and also change their shape time after time.

Our Planet is covered by an ozone layer and has an electromagnetic surface. In fact, that electromagnetic field stops the direct heat particles coming from Sun to Earth. Also, some other elements are also being stopped. Earth consists of north pole and south pole in space. These poles keep the Earth rotating in its cycle.
