Do you know about the volcano? What is this and how does it happen?
What causes make it happen and how many types of volcanoes are there?

In this post, you will get to know all answers to the above-mentioned questions.

Do you ever have an encounter with the place and landscape which is made up of volcano erupted material? If yes, then share your views,  information, and experiences. Which may be helpful to others to inspire and motivate them to carve more about Earth's planet.

Our geographers and scientists used to indulge in the various research of our Earth’s interior and disclose many mystery and truth regarding it, from time to time. The volcanic activities of Earth help them to do so.

The volcano is a sudden catastrophic natural disaster. The volcano is a vent or fissure in the Earth’s crust through which hot magma, lava, volcanic ash and gasses, molten rocks, solid particles, and gasses, came out on the surface of Earth.

Volcanic activities prove that the Earth is extremely hot and in the molten form (mostly) from inside.

The study of volcanoes is called Volcanology.

Before going deep into this topic let’s know about some important terminologies related to the volcano.

Important terminology related to Volcano

Volcanology: The study of volcanoes is known as volcanology, and the person indulges in it is known as a Volcanologist.

Vent or Neck or Conduit: The natural passage (looks like a pipe), through which volcanic eruption happens, is known as a Vent.

Crater: The hole on the surface of the earth’s crust through which magma or lave comes out, is known as a Crater.

Now it’s time to know the reason behind this catastrophic action on earth’s crust.

What are the causes behind volcanic eruption?

  1. The presence of Radio Active elements inside the Earth, which leads to help in generating convection currents and pressure due to the reaction between these radioactive elements, causes a volcanic eruption.
  2. Increase in temperature with the increase in-depth, inside the Earth’s crust, there is an increase of 1 degree Celsius temperature with every 32 meters of depth.
  3. Soft surface: For volcanic eruption soft crust is necessary because volcanoes burst out with soft surfaces.
  4. Earthquakes are also responsible for volcanoes.

Moreover, there are many ways, how volcanoes are helpful for the life on earth.

How Volcanos helps Earth

  • They worked as a safety valve like pressure cookers do to release pressure from the interior of Earth and save us from major destruction.
  • Gives information about Earth’s interior.
  • The formation of black soil is a great gift of the volcano for agriculture. Deccan plateau of India and Washington of the USA are good examples. Black soil is good for growing sugarcane, cotton, tobacco, wheat, and other crops.
  • Formation of Hot springs, which is good for many skin diseases and for other household, construction purposes.

  • Cause to brought expensive minerals like gold, silver, iron, and bronze, etc. on the surface of Earth.
  • Helpful in generating Geothermal Energy.
  • Develop many places of attraction, results in the development of tourism.

  • Creation of natural Lakes, ponds, and water resources.
  • This leads to the formation of Igneous rocks.
  • Formation of new islands.

Disadvantages of the Volcano

  • Mass destruction of life, economy, and land.
  • Cause to lead Earthquake followed by the volcano.
  • In the ocean volcano cause deaths of mass marine life.
  • Loss of agricultural crops.

  • Release of harmful gasses.
  • Destruction of islands due to continuous active volcanic activities.
  • Effect weather due to the eruption of ashes, solid particles, and gasses.

Above are some important causes, advantages, and disadvantages of the volcano. In the post How Volcanoes can be classified, discuss its types on a different basis.
