The style of eruption depends on a number of factors, including the magma chemistry and content, temperature, viscosity (how runny the magma is), volume and how much water and gas is in it, the presence of groundwater, and the plumbing of the volcano.
What factors determine the type of volcanic eruption quizlet?
The type of volcanic eruption is determined by the magma composition, magma temperature, and amount of dissolved gases. List the materials ejected from volcanoes. The materials ejected from volcanoes include lava, gases, and pyroclastic materials, such as ash, dust, cinders, volcanic blocks, and volcanic bombs.
What are the 3 factors that determine the strength of a volcanic eruption?
There are three main factors that influence the violence of a volcanic eruption: 1. magma viscosity, 2. magma temperature, and 3. amount of dissolved gases.
What is one factor that determines how explosive a volcanic eruption quizlet?
The amount of water vapor and other gases present is one factor that determines whether a volcanic eruption will be quiet or explosive.
What is the biggest factor in determining what type of eruption will happen?
Magma composition impacts nearly everything about a volcano, with viscosity of the melt being one of the most important factors that determines eruption dynamics, and even the shape of a volcanic edifice.
What are three factors that determine how violently or quietly a volcano erupts?
The primary factors that determine whether a volcano erupts violently or quietly include magma composition, magma tempera- ture, and the amount of dissolved gases in the magma.
What are the factors that determine the shape and size of a volcano?
Determinants of size and shape
The volume of volcanic products.The interval length between eruptions.The composition of volcanic products.The variety of volcanic eruption types.The geometry of the vent.The environment into which the volcanic products are erupted.
What are the main factors that control whether a volcanic eruption is explosive or nonexplosive?
The amount of dissolved gas in the magma provides the driving force for explosive eruptions. The viscosity of the magma, however, is also an important factor in determining whether an eruption will be explosive or nonexplosive.
What factor best determines what type of volcano will form in a given area quizlet?
Tectonic setting determines the type of volcano. Mid-ocean ridges produce lava plains. Subduction zones produce composite volcanoes. Hot spots beneath oceans produce basaltic shield volcanoes, while hot spots beneath continents produce caldera-forming eruptions and rhyolitic magma.
Which of the following factors help determine whether a volcanic eruption will be violent or relatively tame?
Which if the following factors helps determine whether a volcanic eruption will be explosive or relatively quiet? The amount of dissolved gases in the magma, temperature of the magma, and composition of the magma.
What factor best determines what types of volcano will form in a given area?
The most important factor in determining the shape or type of volcano is the viscosity of the magma that builds the volcano. Viscosity is a measure of a fluid material’s resistance to flow and results from the internal forces and friction between the material’s molecules.
What are the 3 factors that influence how a volcano erupts quizlet?
What primary factors determine whether a volcano erupts violently or quietly? Magma composition, magma temperature and the amount of dissolved gases in the magma.
What are the two primary factors that determine how magma erupts quizlet?
The two primary factors that determine how magma erupts is its viscosity and gas content.
What are the three types of volcanoes?
The Three Classic Types of Volcanoes
Cinder Cone Volcanoes.Composite Volcanoes (Stratovolcanoes)Shield Volcanoes.
