Although, most volcanoes do errupt with lava there are some that explode with mud they are formed as hot water, which has been heated deep below the earth's surface, begins to mix and blend with various subterranean mineral deposits, thus creating the mud slurry exudate. This material is then forced upwards through a geological fault or fissure due to certain local subterranean pressure imbalances. To be literal though they are not considered volcanoes since to be classified as a volcanoe it must spew forth fiery lava, but they do resemble volcanoes in just about every aspect except the lava of course. Look it up on line its pretty amazing to see.

∙ 15y agoAfter an eruption, lava hardens at the top of the channel, forming a plug. As more lava rises, pressure increases. When the plug gives way, there is another eruption which lasts until the pressure drops again. This is often exaggerated by the presence of water in the mixture, which forms steam and quickly increases the pressure. That is what happened at Mt. St. Helen's, blowing out the upper third of the cone on one side and causing a flow of hot mud that covered dozens of square miles.

∙ 9y agoMost do, but not in all eruptions. Many volcanoes, instead of producing lava, erupt clouds of hot ash, rock, and pumice.

Do volcanos erupt differently?
No, not all volcanoes would erupt the same way. Some volcanoes erupt by explosion while others barely trickle lava down the volcano.
What do volcanoes look like at different boundaries?
Volcanoes are holes in the Earth's curst that erupt when lava gets too hot. So when lava starts to boil it starts to look for a hole and epurts.
Why do volcanoes hibernate?
Volcanoes that form islands over hot spots sometimes become dormant because they move away from the hot spot. If they move away from the hot spot, magma is no longer created.
Do oceanic crust hot spot volcanoes tend to erupt more explosively than other volcanoes?
No they do not erupt more explosively. It all depends on the gas and the viscosity. An example is Kilauea in Hawaii because it does not erupt explosively.
Are all volcanoes destructive?
Volcanoes are only destructive to people and property when they erupt. Volcanoes can lie dormant for decades before they erupt. The Hawaiian Islands were all formed from eruptions of volcanoes in the ocean.

What do volcanoes create?
Volcanoes create land by when they erupt the lava melts and turns into gravel and then forms the lands.
What is lava flow?
It's the molten rock that comes out of volcanoes when they erupt and that streams downhill while it's still so hot that it is liquid.
What do all vocanoes share together?
All volcanoes share together the ability to erupt and spew lava. They contain moulted rock which is extremely hot. Some volcanoes are considered to be extinct due to the length of time they have gone since the last eruption.
Do volcanoes erupt once a lifetime?
A volcano can erupt many times. If the pressure from below builds up too much, the volcano will erupt, throwing out very hot gases and lava, until the pressure has been released.
What makes a volcano to erupt?
the hot lava
Where do more active volcuranos ocurr?
Active volcanoes are found on mainly plate margins, with the few examples of hot spots all over the place (e.g. Moana Loa on Hawaii). Volcanoes found at constructive plate margins are more effusive and erupt basaltic lava (e.g. Iceland) and volcanoes found NEAR destructive plate margins are explosive and erupt either andesitic or rhyolitic lava (e.g. Mount Saint Helens-however this volcano might not erupt for quite a while whereas the other two example erupt very frequently).
What are volacanoes?
A volcano is a mountain or hill and in most cases hot lava erupts from them due to the pressure and energy released inside the Earth. When ash and gases try to escape they erupt into lava which comes from volcanoes.
Why do the volcanoes have to be hot?
because they have to be hot when the lava spils
Do oceanic crust hot spot volcanoes tend to erupt more explosively than other volcanoes?
No they do not erupt more explosively. It all depends on the gas and the viscosity. An example is Kilauea in Hawaii because it does not erupt explosively.
