The style of the volcanic eruption is very dependent on the amount of dissolved gas that is in the magma (liquid rock below the surface). If there is a high gas content the volcanic eruption will be explosive and create a log of ash. If the gas content is low the eruption produces more lava flows.
An example of a high gas content eruption was the last major eruption of Mt. St. Helens in 1980.
An example of a low gas content eruption would be the Hawaiian volcanoes.
What else can I help you with?
Do all volcanoes erupt lava?
Lava emissions are found with all active volcanoes, although some volcano emit more lave than others.
What shoots out of a volcano during an eruption?
It depends on the type of eruption. Some will erupt lava or a mixture of lava and gas. Others will erupt gas, ash, and pumice.
Do volcanos erupt differently?
Yes, volcanoes can erupt in different ways depending on factors such as the type of magma, the presence of gas or water, and the size and shape of the volcano. Eruptions can range from explosive, where magma is fragmented into ash and rock, to effusive, where lava flows steadily from the volcano. Each eruption type presents unique hazards and impacts.
How many times does volcanoes go off?
The frequency of volcanic eruptions varies depending on the volcano. Some volcanoes erupt frequently, while others may remain dormant for hundreds or thousands of years. It is difficult to predict exactly how many times a volcano will erupt in the future.
How fast does a volcano erupt?
The speed of a volcanic eruption can vary greatly depending on the type of volcano and the specific circumstances. Some volcanoes can erupt explosively, sending ash, gas, and rock fragments high into the air at speeds of hundreds of miles per hour, while others may have slower, more effusive eruptions where lava flows steadily from the vent. Eruptions can last anywhere from a few minutes to several weeks or even longer.
Do all volcanoes erupt lava?
Lava emissions are found with all active volcanoes, although some volcano emit more lave than others.
Why do some volcanoes erupt while others erupt quietly?
This is because of the time of volcano it is and the type of lava it excretes. A steep volcano will erupt with basaltic lava which is runny and can clog at the top. A shield volcano, however is different as the thick lava emitted just glops onward.
How bad are the damages after a volcano just erupt?
Depends on the size of the volcano and the clumps of lava, some volcanoes dolittle damage but some volcanoes destroy entire villages
Do all volcanos erupt?
no all the volcanoes do not erupt.there are three types of volcanoes extinct,average and active. no because there are dome mountains that do not erupt and they are full of lava and they will erupt in more or less than 300 years.

What type of volcano does and does not erupt?
Active volcanoes erupt. Dormant volcanoes are quiet - but may erupt again some day. Extinct volcanoes have "closed up shop" for good, and will never erupt again.
How do you use Volcano in a sentence?
A ring of volcanoes surrounds the northern Pacific Ocean, some of which are active and spew lava and others of which are dormant mountain peaks.

Do volcanoes erupt after 10 centuries?
Some do. Most volcanoes will erupt more frequently than that, but some do go 1000 years or more between eruptions.
Can a volcano erupt twice?
Yes, a volcano can erupt multiple times throughout its lifespan. Volcanic eruptions occur when pressure builds up within the magma chamber beneath the volcano, causing it to release lava, ash, and gases. Some volcanoes can remain active for years or even centuries, erupting multiple times during that period.
