Hm? It appears there's red, glowing liquid coming out of that "thing". Oh well.
How they Erupt
Wha-Oh god no pls NO! why tho (;-;")
How am I even still alive? And how'd a get here? I thought I got hit by a fireball. :)
Volcanoes are ruptures in the Earth's crust that allow magma, volcanic gases like carbon dioxide, and ashes to spew out of the mantle of the Earth and onto the surface of the crust. They usually form on the boundaries of the tectonic plates on Earth's crust.
No why. why you do diss ;-;
Magma is stored in large magma chambers. When the pressure in those chambers gets too high, magma starts to get pushed upwards through the crust and out of the surface of the crust. (do to capillary action, which is how liquids, when under pressure, take the path of least resistance) This process could take days,but when it's done, the explosion could have devastating effects.
After a volcanic eruption (one that's underwater), the magma from volcanoes eventually cools down, in which cooled magma would gather in one general area and form into solid rock. Eventually, the pile of cooled magma, which is now rock, would pile with more rock/cooled magma that it would rise above the water, forming a new island!
Hotspots are places below volcanoes that store and create magma through heating up cooled rocks/cooled magma. They are the reason why volcanoes even spew out magma.
Lahars are caused by volcanic eruptions. Water next to volcanoes flows down the mountain/hill side and mixes with mud creating a law, to which then they flow down and drown and crush anything in the way of the Lahar.
Wheh why da mud now ('-')
These are a few terms that are used for volcanoes.
