When certain types of volcanoes erupt, their lava is so full of gas that when it reaches the surface it froths and explodes.
The explosions hurl the pulverised (now cooled and solidified) magma high up into the atmosphere.
The pulverised rock is so fine it is called "volcanic ash" and this forms a cloud above the volcano that then drifts off with the wind. This is a volcanic ash cloud.
See image of a cloud in the related link below.
What else can I help you with?
Do volcanoes produce large amounts of ash when they erupt?
Volcanoes with high levels of water in their lava produce ash, those with dry lava produce no ash.
What does the ash rock and dust from volcanoes cause?
its called tides
Do shield or composite or cinder cone or caldera volcanoes have alternate layers of ash and lava?
Composite VolcanoesComposite Volcanoes. Composite volcanoes are tall, cone shaped mountains in which alternate layers of lava alternate with layers of ash. This happens when smooth lava flows alternate with explosive eruptions of lava fragments.
How do ash cloud volcanoes form?
Ash cloud volcanoes form when explosive eruptions occur that release large amounts of ash, volcanic gases, and rock fragments into the atmosphere. These eruptions are typically driven by the release of built-up pressure from the magma chamber within the volcano. The ash can be carried long distances by wind, creating hazardous conditions for aviation, agriculture, and human health.
What is it called when ash and cinders are blown violently out of volcanoes?
when volcanic ash bursts out of the volcano, its called an eruption.^^^Actually, when ash and cinders are blown violently out of volcanoes, it's called a tephra. :3
What are ash clouds emitted from?
Ash clouds are emitted from volcanoes.
Do composite volcanoes blow out smoke and ash or lava?
ash
Four landforms created from lava and ash?
Three landforms that can be created from ash are cinder cone volcanoes, composite volcanoes, and shield volcanoes. Lava plateaus can also be formed.
Do volcanoes produce large amounts of ash when they erupt?
Volcanoes with high levels of water in their lava produce ash, those with dry lava produce no ash.
Do all volcanoes erupt with ash?
no
Shield volcanoes are known for their?
Ash production
Why do volcanoes effect planes?
After volcanoes erupt, a huge cloud of ash rises above it. This ash cloud causes problems for aeroplanes in mid flight.
Do volcanoes erupt just lava?
No. Volcanoes also release ash and a variety of gasses.
Name three things that can come out of volcanoes?
Volcanoes can produce lava, ash, and gas.
What makes composite volcanoes to erupt?
Ash and Gas make composite volcanoes erupt i believe
Where does the volcanoes emit come from?
Volcanoes can emit lava,rocks,ash,fragments and molten rock.
Why do volcanoes make ash?
cuz there wicked hot!
