What else can I help you with?
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.
The hotter the magma or lava the greater lower visiosity?
Yes, that's correct. Hotter magma or lava has lower viscosity because the higher temperature reduces the internal friction between the molten rock particles, allowing them to flow more easily. This results in a more fluid-like behavior and faster movement of the magma or lava.
Is basaltic magma or granitic magma hotter?
Baslatic magma is hotter.
Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
What Tend to increase the explosive potential of magma body beneath a volcano?
high viscosity and dissolved gas
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 is the difference in silica content and viscosity between light-colored 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.

How does temperature affect viscosity and magma?
Temperature affects viscosity of magma by influencing the mobility of its molecular structure. Higher temperatures decrease viscosity by increasing molecular motion and breaking down intermolecular forces. This leads to more fluid magma. Conversely, lower temperatures increase viscosity by reducing molecular motion and strengthening intermolecular interactions, resulting in more viscous magma.

How does temperature effect magma?
Temperature affects magma by influencing its viscosity, or thickness. Higher temperatures result in lower viscosity, making the magma more fluid and allowing it to flow more easily. Lower temperatures increase viscosity, causing the magma to be more viscous and difficult to flow. Ultimately, temperature plays a significant role in determining the behavior of magma during volcanic eruptions.
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.
