FORMATION OF THE EARTH AND NOON THE UNIVERSE
FORMATION OF EARTH AND MOON HISTORY OF EARTH The formation of the Earth is related to the formation of the solar system. The gases that form the solar system gradually started shirking increasingly more matter gathered in the centre while temperature was constantly increasing. The sun formed from this condensed molecular cloud of dust. Due to rapid rotation the rest of the clouds scattered and flattened into an aur orbiting protoplanetary disc around the sun. The dust particle in the protoplanetary disc collided and stuck together due to electrostatic attraction forming planetesimals. When there is a size about one kilometre they collided due to mutual gravity forming proto planets which were a few thousand kilometres in diameter. THE EARTH PLANET This is how the Earth was formed 4.6 billion ago. Around a hundred and seventy million years after the formation of Earth a similarly young planet known as Thea Struck the Earth's still soft crust. Thea was demolished after t...
