Water vapor is a constant component of the volcanic emissions. This water vapor is believed to be from the early steam from the interior of the earth's mantle. Active volcanoes serve as an outlet for all the pent up vapor.

∙ 7y agoThere are two potential sources. First, stratovolcanoes are most commonly found near subduction zones, where oceanic crust slips into the mantle. This crust takes some seawater with it where the water then mixes with mantle rock. Second, water can seep down into the volcano from outside either from precipitation or, in the case of island volcanoes, the ocean.

Name two things which are expelled from a volcano?
There are several things which come out of a volcano when it erupts. The two main things are lava and gases.
What is a small hole inside the crater of a volcano that releases gases called?
A small hole inside the crater of a volcano that releases gases is called a fumarole. Fumaroles are openings in the Earth's crust where volcanic gas and steam are emitted. They often release gases such as sulfur dioxide, hydrogen sulfide, and carbon dioxide.
When a volcano erupts where does the lava ash and gases come from?
lava, ash and gases come from the centre of the earth where they have been kept for a very long time and they become so cramped that they have to find a way out so they form volcanos.

What is uncombustion gases in steam ejector?
Incondensible gases, are gases that do not condense and do not dissolve readily in hot water. Steam ejectors are used to remove these gases from a condenser.
What is another word for the hole or vent at the top of a volcano?
Fumaroles are vents from which steam and volcanic gases escape into the atmosphere.
What is the definition of the word volcano?
A vent in the earth's crust through witch lava, steam, ash, and etc come poring out.
When a volcano erupts where does the lava ash and gases come from?
lava, ash and gases come from the centre of the earth where they have been kept for a very long time and they become so cramped that they have to find a way out so they form volcanos.
