How do volcano erupt?

Volcanoes are formed when there is a great stress inside the earth’s crust and the pressure of magma reaches so high that it finds its way upward causing an eruption. Sometimes the magma chamber breaks its sides and only reaches to the flank or summit of volcano and sometimes reaches to the surface causing an eruption. In the volcanoes which are not much active supply the magma from the deeper parts of the earth is not sufficient to cause eruption so most of the times crystals forms and they go down at the bottom releasing gas in the form of bubbles which come to the top of chamber and sometimes the pressure created by these gas bubbles are enough to erupt a volcano or just wait there for a little more push which they get from the next new magma formed within the earth. The heat just triggers the magma for eruption which was there for a long time.

Magma is the melted rocks deep in the earth crust. The rocks melt because of great heat inside and forms a thick liquid called magma and when it comes to the surface it is called as “lava” and flows into the air in the form of ashes etc.

If the volcanic eruption is explosive then the matter forms a cloud of hot tephron. The things coming in its way are almost destroyed. Ashes which are released in the sky fell on the earth in the form of powdery snow and it doesn’t melts. A huge mass of snow can cause harm to the vegetation, living organism and human beings.

The intensity of explosion depends upon the thickness of magma. The gases cannot escape easily. Hence they are accumulates inside till they get enough heat energy for the explosion.

  1. the information is splendid but too less. It is very useful specially for projects

  2. This site is very useful and the information is great. I would certainly recommend it to my students.

  3. I love your website

  4. information given is good ,not detailed but ok.

  5. hi nice informational text very ideal

  6. I just copy and paste the whole thing for a simple science report……thanks, no work for me!!!

  7. hii, luv this website! helped meh alot seeing as i had to write a very science report and all tha info is there.
    thnk yhu

  8. i used this for a school project …….got lots of helpful info

  9. i love your website

  10. This website is a great source. My work is more efficient, thanks to this website!

  11. Your site is great i would use it for my school!

  12. Great site.
    It helped me with my science project.
    I got an A+.

  13. Thanks for the help :)
    Used this for my science project too!

  14. thanks you gave me another idea and information to my studies and assingments and projects too

  15. wowz this website was awesome. helped meh so muches when i needed to do a school assignement. Love love love it! IT was ahhhhmazing. i wonder how you got this info, must have went into a real volcano! I always have wanted too so maybe ill take your lead and go into one!:)
    Love, Kitten xoxo

  16. thanks for the info like
    :-)

  17. love the site iam in…….its really useful…… :)

  18. I love this website it is awesome!! I’m useing it for my science progect. : O

  19. this really really really really really really helped me with my science project

  20. awsome site i got a A+++ she said how she said how awsome it was and will post it on her site thanks u dicks

  21. this really helps

  22. I think that much more explanation with the diagram

  23. i love the information given out simple not complicated, but is lacking! so i suggest more basic information should be given out.

  24. thank you so muchh….ahhh it helped so much.

  25. this is so good this can help me get a A+ in my science class and this helps us with our educatoin

  26. I think that a volcano can errupt by the way it has enough energy to build up a bigger volcano that will errupt faster as the magma rises on top of the the volcano.

  27. Hi this is good info it helped me alot thx

  28. Why is that when the volcanoes erupt all of that red stuff comes out .And why do people that see were volcanoes move their by them. Is that just dumb or what. So can you answer my question. And would it be good if i do a science fair project it wii be how does volcanoes erupt and why do they erupt. And thats all i wanted to ask you is why do the volcanoes erupt and this is by;” Brianna Marie Thomas.

  29. Good for findidng out how to answers questions to my teacher. hehe

  30. This site is great as for me a ten year old child we have got to search how Volcanoes Erupt and i just opened my laptop to see and here comes this site i just hope my teacher likes it.
    But i was just asking if you could put more information , but rather than that its adorable!!

  31. good, informative, but with a few grammar mistakes. i edited it for a school project, its not brilliant, but at least theres correct grammar;
    Volcanoes are formed when there is great stress inside the earth’s crust and the pressure of magma reaches a critical point where it finds its way upwards, causing an eruption. Sometimes the magma chamber breaks its sides and the magma only reaches the flank or summit of the volcano and sometimes reaches the surface causing an eruption. In the volcanoes which are not as active the supply of magma comes from deeper parts of the earth. It is not usually sufficient enough to cause an eruption, so most of the times crystals form and go down to the bottom, releasing gas in the form of bubbles which come to the top of chamber and sometimes the pressure created by these gas bubbles are enough to erupt a volcano or just wait there for a little more push which they get from the next new magma formed within the earth. The heat just triggers the magma for eruption which was there for a long time.
    Magma is the melted rocks deep in the earth crust. The rocks melt because of great heat inside and form a thick liquid called magma. When it comes to the surface it is called lava and flows into the air in the form of ash, dust, rocks et cetera.
    If the volcanic eruption is explosive then the matter forms a cloud of hot tephron. Anything in its way is destroyed. Ashes which are released in the sky fall on the earth in the form of “powdery snow” which doesn’t melt. A huge mass of this “snow” can cause harm to the vegetation, living organism and human beings.
    The intensity of explosion depends upon the thickness of magma. The gases cannot escape easily, so they accumulate inside until they get enough heat and energy for the explosion.

  32. cool this helped me on my project ;D

  33. cool facts hope to learn more about volcanos and hope to get a good grade on my project
