  • Nature has its own way of expressing grief,
    anguish, frustration and intolerance. Is a
    volcano one of these unspoken expressions of
    nature? Is it a good phenomenon or a bad sign for
    mankind? What is it actually made up of? You will
    find your answers in this article.
  • Volcanoes are classified into three types. They
    are shield volcano, stratovolcanoes, and cinder
    cone volcanoes. These were formed based on the
    types of eruption, intensity, heir nature of
    occurrence, and the quantity of outlet from the
    earths crust.

  • Shield volcanoes erupts viscous lava in such
    quantities that it flows many kilometres.
    Stratovolcano on the other hand erupts different
    types of lava along with rock pieces and ashes in
    the sky.
  • Where does it start? It all begins about 30
    kilometres under the earth where the core is
    stored up with hot lava.
  • This region is so hot and light in weight that it
    can squeeze out from the rocks cracks to form a
    giant rock bubbles that we call a volcano
  • Volcanoes also have their own stories to say.
    Active volcanoes are those that have happened in
    the history of mankind many years ago and had a
    significant impact.

  • A dormant volcanoes is also an historic volcanoes
    but they also have the potential to erupt
    multiple number of times and has occurred at
    least once in the recent past
  • An extinct volcano is one which has occurred once
    in the past but has very less probability of
    reoccurrence anytime in the future.
  • Volcanoes are dangerous as they release so many
    poisonous gases, ashes, red molten lava that is
    capable of spreading a large surface area
    destructing farmlands, houses and polluting the
    environment to an extend that life becomes
    difficult in the surrounding regions
