Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
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
Higly explosive volcanoes tend to have what type of magma?
Magma with high silica, high viscosity, and higher gas content.
What conditions make for a violent volcanic eruption?
Magma with high silica content
Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
What properties of magma help to determine the type of eruptions?
The properties of magma that help to determine the type of eruption are the magma's viscosity and its silica content. Those volcanoes that exhibit massive eruptions have a high viscosity and high silica content.
How does temperature affect viscosity magma?
High temperature=low viscosityLow temperature=high viscosity
Does temperature affect viscosity of magma?
High temperature=low viscosityLow temperature=high viscosity

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.
Do shield volcanoes have high viscosity?
No. Shield volcanoes are fed by low-viscosity basaltic magma.
Why does magma erupt effusively?
Due to high gas content and high viscosity.
