What else can I help you with?
Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
What two factors control the explosiveness of an eruption?
The explosiveness of an eruption is primarily controlled by the viscosity of the magma and the amount of gas trapped in it. Low viscosity magma with high gas content tends to lead to more explosive eruptions, while high viscosity magma with lower gas content leads to less explosive eruptions.
What is magma composition of Mount Tambora?
It is that it has high silica content
How does the viscosity of magma contrast Krakatoa?
The viscosity of magma affects its ability to flow. For Krakatoa, the magma was characterized by high viscosity due to its high silica content, causing pressure buildup leading to explosive volcanic eruptions. The high viscosity of the magma at Krakatoa contributed to the violent nature of its eruptions in 1883.
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.
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.
Does temperature affect viscosity of magma?
High temperature=low viscosityLow temperature=high viscosity
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
What is meant by the term viscosity when used in describing magma?
The ease with which it flows or how thin or thick it is. the more solid it is the higher the viscosity. As in Oil the thicker it is the higher the viscosity machine oil low viscosity, gearbox oil 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.
