What else can I help you with?
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
Is thick and sticky a physical property of magma from an explosive eruption?
Yes, magma viscosity (thickness) and stickiness can be physical properties of magma from explosive eruptions. Higher viscosity and stickiness can lead to explosive eruptions because gas bubbles are trapped in the magma, building up pressure until a violent release occurs.
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.
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.
Is viscosity a chemical or a physical change?
viscosity is a physical characteristic not a physical change. it is the thickness of a substancephysical changes would be if it turned from solid into a liquid.for example a chocolate bar goes through a physical change when it becomes melted chocolate.

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.

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.
Viscosity is a property in which state of matter?
yes viscosity is a property of gas
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 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.
