Which conditions make for a violent volcanic eruption?
Magma with low viscosity
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What role did viscosity play on the volcanic eruption?
Viscosity of magma affects the explosivity of a volcanic eruption. High-viscosity magma tends to trap gas bubbles, leading to pressure build-up and explosive eruptions, while low-viscosity magma allows gas to escape more easily, resulting in effusive eruptions. Ultimately, the viscosity of magma influences the type and intensity of volcanic activity.
What condition make for a week volcanic eruption?
The answer is : Magma with low viscosity. It makes for a weak volcanic eruption. If the viscosity is low (thin), non-explosive eruptions usually begin with fire fountains due to release of dissolved gases. When magma reaches the surface of the earth, it is called lava.
What was Krakatoa's viscosity?
Krakatoa's magma viscosity was estimated to be relatively low, indicating it was more fluid-like. This low viscosity contributed to the violent explosive eruption in 1883, producing devastating volcanic events such as pyroclastic flows and tsunamis.
What are three factors that affect the violence of a volcanic eruption?
Three factors that affect the violence of a volcanic eruption are the composition of the magma (viscosity and gas content), the location of the eruption (proximity to populated areas), and the type of volcano (shield, cinder cone, stratovolcano).
What determined how strong a volcanic eruption will be?
The viscosity of the magma
What is the difference between viscosity and volcanic erutions?
Viscosity refers to a fluid's resistance to flow; fluids with high viscosity are thicker and flow more slowly. Volcanic eruptions, on the other hand, involve the expulsion of magma, gases, and ash from a volcano. Viscosity can affect the explosiveness or effusiveness of a volcanic eruption, as more viscous magmas typically lead to more explosive eruptions.

How viscosity affect volcanic eruptions?
Viscosity is how thick the magma is and this can impact on how much a volcano erupts and how it flows.

What are the two important factors that affect the explosiveness of a volcanic eruption?
Pressure and magma
Why do volcanic eruptions differ?
The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.
What was Krakatoa's viscosity?
Krakatoa's magma viscosity was estimated to be relatively low, indicating it was more fluid-like. This low viscosity contributed to the violent explosive eruption in 1883, producing devastating volcanic events such as pyroclastic flows and tsunamis.
How do differences in magma affect volcanic eruptions?
Differences in magma composition, such as viscosity and gas content, can affect the explosivity of a volcanic eruption. Magma with high viscosity tends to trap gas bubbles, leading to more explosive eruptions, while low-viscosity magma tends to flow more easily and result in gentler eruptions. Additionally, variations in gas content can influence the violence of an eruption by affecting the build-up of pressure within the magma chamber.
