Material that forms magma contains a lot of dissolved gas. When this dissolved gas expands it forms small gas bubbles called vesicles.
The more gas bubbles contained in the magma, the more violent the eruption. In magmas with a higher temperate gases remain dissolved, lowering its viscosity. A higher temperature also means a lower density - lava will be runny (less viscous).
When temperatures are lower crystallisation occurs, forming a more solid magma with a much higher viscosity. In viscous magmas the gases have a more difficult time escaping, causing a more violent eruption.
What else can I help you with?
Does temperature does temperature affect viscosity of magma?
High temperature=low viscosityLow temperature=high 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.
What is the relationship between silicon content and the viscosity of magma?
Higher silicon content in magma leads to higher viscosity. This is because silicon tetrahedra form polymerized chains that hinder flow, making the magma more viscous. Lower silica content results in lower viscosity magma.
What does not affect the viscosity of magma amount of gases silica content temperature all of these affect the viscosity of a magma?
All of these factors affect the viscosity of magma. The amount of gases can influence the fluidity, while the silica content directly impacts thickness, and temperature affects the overall mobility of the magma. Therefore, none of these factors can be excluded as they all play a role in determining 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.
What is relationship between silica content and viscosity?
magma that has more silica is more viscous

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.
What is a magma's viscosity directly related to?
A magma's viscosity is directly related to its temperature and silica content. Higher temperature and lower silica content typically result in lower viscosity, making the magma more fluid and runny. Conversely, lower temperature and higher silica content lead to higher viscosity, resulting in a thicker, more sticky magma.

Therefore, none of these factors can be excluded as they all play a role in determining viscosity.
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.
