The viscosity of lava during an effusive eruption is generally low, allowing it to flow easily and spread over large areas. This low viscosity is typically associated with basaltic lava, which has a high temperature and low silica content. As a result, effusive eruptions tend to produce gentle lava flows rather than explosive activity. The fluid nature of the lava contributes to the formation of broad, shield volcanoes.

What types of lava will most likely lead to a volcanic eruption of an effusive nature?
Shield volcanoes have effusive eruptions. Effusive eruptions are a volcanic phenomenon; in some ways the opposite of explosive eruptions. An effusive eruption is characterized by an outpouring of low viscosity lava which has a fairly low volatile content. Usually, shield volcanoes have effusive eruptions.
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 factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What type of eruption does mt santa maria have?
Mount Santa Maria in Guatemala has experienced both effusive and explosive eruptions in its history. The 1902 eruption was explosive, causing catastrophic destruction, while subsequent eruptions have been effusive with lava flows.
What is viscosity and how does is affect volcanic eruption?
Viscosity is a measure of a fluid's resistance to flow; in the context of magma, it determines how easily it can move. High-viscosity magma, often rich in silica, tends to trap gas and pressure, leading to explosive eruptions. Conversely, low-viscosity magma allows gases to escape more easily, resulting in effusive eruptions where lava flows steadily rather than explosively. Thus, viscosity plays a critical role in shaping the nature and intensity of volcanic eruptions.

What are the 2 types of volcanic eruption?
There are effusive eruptions and explosive eruptions.
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What kind of eruption produces AA?
A'a is associated with effusive (quiet) eruptions.
What is a volcanic eruption called?
Effusive eruptions >:3 WPCMSAdv. Gif. Science
What is the eruption type for Mount Vesuvius?
usually when it erupts its pretty much effusive or explosive
What is a volcanic quiet eruption called?
Effusive eruptions >:3 WPCMSAdv. Gif. Science
What makes a quiet eruption different from an explosive eruption?
quiet eruption flows easeir cause it has a low viscosity and lava flows easier but explosive eruption has a high viscosity and lava flows slower
What type of eruption does mt santa maria have?
Mount Santa Maria in Guatemala has experienced both effusive and explosive eruptions in its history. The 1902 eruption was explosive, causing catastrophic destruction, while subsequent eruptions have been effusive with lava flows.
What do lava flows made of pahoehoe and AA indicate about the type of volcanic eruption that occured?
They indicate that an eruption is effusive rather than explosive.
