Highly viscous magma produces explosive volcanoes, which can quickly move huge volumes of material which could be impossible to escape.
Highly fluid magma tends to produce slow moving, flowing lava, which does not create the destruction associated with explosive volcanoes.
Composite volcanoes are highly variable in what they erupt. Most often, eruptions will release clouds of ash, pumice, and rock fragments. In some cases they fountain or extrude lava.
A composite volcano or Strata Volcano.
it was a neck of a volcano
Mount Fuji is a composite volcano.
mount etna is a volcano in italy
If the magma is more viscous, the eruption is stronger.
Viscous lava ( such as in the caribbean
Shiveluch is a stratovolcano, also known as a composite volcano, characterized by steep slopes and explosive eruptions due to its viscous magma.
very or highly viscous magmas formed it
The Karymsky volcano is a stratovolcano, which is a type of composite volcano. These volcanoes are characterized by their steep slopes and explosive eruptions due to the presence of viscous magma.
a dome volcano is not the same as a cone volcano. a dome volcano is a type of volcano, is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Usually it extrudes very slowly, but constantly. A cone volcano has an appearance of an upside-down funnel with a hole in the top which the lava shoots out of.
No, Mount Nyiragongo is a stratovolcano, also known as a composite volcano. It is characterized by its steep-sided cone shape and explosive eruptions due to the presence of viscous magma.
Viscous lava is very sticky and thick and is more felsic (ie it contains more silica) than non-viscous lava. This type of lava makes for a very explosive volcano, because it's so sticky that it sticks to itself and can't exit the volcano until it explodes violently. Non-viscous lava is more runny and is more mafic (has more iron, less silica). Volcanoes with non-viscous lava are less explosive because the lava just runs out slowly and no pressure builds. The Hawaiian islands are formed from volcanoes with non-viscous lava.
Galeras is a Strato/Composite volcano because of it's gently sloping sides.
A stratovolcano, also known as a composite volcano, is the type of volcano that occurs along a convergent plate boundary. These volcanoes are typically steep-sided and have explosive eruptions due to the presence of viscous magma.
Acid Lava Dome is a type of volcano that forms when viscous acid lava solidifies quickly to form a volcano with steep convex sides.
Mt. Etna is a composite volcano, also known as a stratovolcano. It is characterized by its steep profile and explosive eruptions due to the presence of viscous magma rich in silica.
