Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
Which conditions make for a violent volcanic eruption?
Magma with low 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.
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.
Does an increase in silica increase the viscosity of magma?
Yes. Viscosity is the resistance of a fluid to flowing. A high viscosity means low flowing (I specifically mention this because this is a huge pitfall) When silica content increases, and when temperature decreases, the viscosity of a magma increases along with it.
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.
How far can Kilauea the volcano erupt?
That depends on the forc of the eruption and the viscosity of the magma.
Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
Which conditions make for a violent volcanic eruption?
Magma with low viscosity
What conditions make for a violent volcanic eruption?
Magma with high silica content
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.

What type of magma is primarily associated with high viscosity?
Granitic magma
The viscosity of magma depends upon its silica content and its?
The viscosity is also dependent on temperature. Higher Temperature results in lower viscosities typically, i.e more runny.
What is the difference in silica content and viscosity between light color and dark colored magma?
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
