What igneous rock or magma has the lowest silica content?
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.Read more: Which_igneous_rock_out_of_granite_basalt_andesite_and_peridotite_has_the_lowest_silica_SiO2_content
What type of magma is primarily associated with high viscosity?
Granitic magma
Is a pyroclastic material high or low-viscosity?
Pyroclastic material can form with magma of any composition, but it is more likely to form with high-viscosity magma.
What is the viscosity of magma in a pyroclastic flow?
In a pyroclastic flow, the magma would almost always be considered high-velocity. The velocity and strength of the magma is a result of its chemical composition.
Does temperature does temperature affect viscosity of magma?
High temperature=low viscosityLow temperature=high viscosity

What conditions make for a violent volcanic eruption?
Magma with high silica content
What are the magma types in order of decreasing viscosity?
Most viscous Felsic magma i.e. rhyolite Intermediate magma i.e. andersite Mafic magma i.e. Basalt Ultramafic magma i.e. Komatiite Least viscous
What type of magma is primarily associated with high viscosity?
Granitic magma
How does temperature affect viscosity magma?
High temperature=low viscosityLow temperature=high viscosity

Does temperature does temperature affect viscosity of magma?
High temperature=low viscosityLow temperature=high viscosity
Which property of magma will change the viscosity?
Silica content determines viscosity. The higher the silica content the more viscous (slower moving). Ultramafic <45% silica Least viscous Mafic 45-52% Silica Intermediate 53-65% Silica Felsic >65% Silica Highly viscous
Is pyroclastic material likely to form from low- viscosity or high - viscosity?
Pyroclastic material is more likely to form with high viscosity magma.
What determines the viscosity of magama?
temperature, silica content, and the amount of dissolved gases determine the viscosity of magma. For instance, if the magma is cold, has a high amount of silica and has lots of dissolved gases in it the viscosity will be very high.
