Typically, yes. Larger volcanoes such as shield volcanoes erupt more frequently than smaller ones. However, the speed of eruption depends on the type of volcano and lava. If the volcano is an acid-lava volcano or a composite volcano, the eruption may be slow and noisy and the acidic lava is viscous, which means it flows slowly, and that it solidifies up the vent and block the lava from flowing out easily, creating a huge "BANG" during eruptions.
What else can I help you with?
Which conditions make for a violent volcanic eruption?
Magma with low viscosity
What is the relationship between the viscosity of a magma and its temperature?
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.
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.
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.
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 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 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.
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.
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 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.
How does the viscosity of the magma influence the type of eruption?
The viscosity of magma affects whether or not magma flows away or piles up during an eruption. Viscosity, along with volatiles (dissolved gases) and volume determine whether you have a peaceful eruption or a very violent one.
What two things determine the viscosity of magma?
The viscosity of magma is primarily determined by its composition and temperature. Higher silica content increases viscosity, making the magma thicker, while lower temperatures also contribute to greater viscosity. Conversely, magma with lower silica content and higher temperatures tends to be more fluid. Additionally, the presence of dissolved gases can influence viscosity by reducing inter-particle friction.
What factors affect magma's viscosity?
The two main factors that affect viscosity are temperature and silica content. Higher temperatures lower viscosity while higher silica content increases viscosity.
