Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
The viscosity of magma depends upon its silica content and its?
temperature. Magma with higher silica content tends to have higher viscosity, while temperature can also affect viscosity by influencing the mobility of the magma's mineral components.
Is it true how easily magma flows depends on its visocisty?
Yes, the ease of magma flow is influenced by its viscosity. Magma with low viscosity (more fluid-like) flows more easily, while magma with high viscosity (more sticky) tends to flow less easily and may lead to explosive volcanic eruptions. Viscosity is mainly determined by the magma's temperature, composition, and gas content.
Which conditions make for a violent volcanic eruption?
Magma with low 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.
How far can Kilauea the volcano erupt?
That depends on the forc of the eruption and the viscosity of the magma.
What 3 factors determine magma viscosity?
The three elements that determine viscosity in magma are:TemperatureSilicaOxides (gases)Viscosity changes the way in which magma will flow. Magma with low viscosity will flow much more easily than high viscosity magma.

Correct order of decreasing magma viscosity?
The amount of viscosity present in magma depends on the amount of silica it has. A composite volcano produces rhyolitic lava which is very thick. A shield volcano produces a basaltic lava with less silica and significantly less viscosity.
What does viscosity have to do with eruptions?
The viscosity of magma or lava will determine whether or not the eruption is explosive or quiet. Higher viscosity magma can result in explosive eruptions. Lower viscosity magmas tend to flow more freely.
What mainly determines the viscosity of a magma?
Viscosity is the measure of a liquids resistance to flow. In the case of magma, the hotter it is, the lower the viscosity.
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.
How forceful an eruption is depends on the composition of the?
magma within the volcano. Magma with high gas content and high viscosity tends to create more explosive eruptions, while magma with lower gas content and lower viscosity leads to less forceful eruptions. Additionally, the presence of water can also influence the explosiveness of an eruption.
