Answer:

The Big Bang theory was proposed to explain the origin of universe. According to this theory, the origin of universe took place due to a single huge explosion in the space due to which the various galaxies were formed in it.

Its various postulates were :

  • The earth formed about 4.5 billion years back.
  • There was no atmosphere on early earth.
  • Water vapour, methane, carbon dioxide and ammonia were released from the molten mass which came out of earth due to volcanic eruptions.
  • The UV rays broke up water into Hydrogen and Oxygen.
  • The ozone layer formed from oxygen slowly
  • Water vapour condensed fell down as rain, to fill the depressions and form oceans.
