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 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 are the two factors control the explosiveness of a volcano?
The viscosity of the magma and its gas content.
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.
WHAT ARE THE THREE TYPES OF MAGMA AND THE DIFFERENCES?
The three types of magma are basaltic, andesitic, and rhyolitic. They differ in their silica content, viscosity, and eruptive behavior. Basaltic magma has low silica content, low viscosity, and tends to erupt quietly, while rhyolitic magma has high silica content, high viscosity, and tends to erupt explosively. Andesitic magma falls in between these two in terms of composition and behavior.
What two factors control the explosiveness of an eruption?
The explosiveness of an eruption is primarily controlled by the viscosity of the magma and the amount of gas trapped in it. Low viscosity magma with high gas content tends to lead to more explosive eruptions, while high viscosity magma with lower gas content leads to less explosive eruptions.
What two main factors affect magmas viscosity?
The main factors that affect magma's viscosity are temperature and silica content. Higher temperatures generally result in lower viscosity, as the magma becomes more fluid. Lower silica content also leads to lower viscosity, as silica molecules tend to create more resistance to flow.
What are the two factors the control whether a volcano eruption will be explosive or quiet?
The two main factors that control whether a volcano eruption will be explosive or quiet are the viscosity of the magma and the presence of dissolved gases. High viscosity magma (thick and sticky) and high gas content tend to result in explosive eruptions, whereas low viscosity magma (thin and runny) and low gas content lead to quiet eruptions.
What factors determine if a volcanic eruption will be quite or explosive?
The two main factors are the viscosity and the gas content of the magma. explosive eruptions usually occur when magma approaches the surface and dissolved gasses bubble out so rapidly that it escapes explosively, creating clouds of ash and pumice. If there isn't enough gas this can't happen. High viscosity magma by definition does not flow easily. This allows pressure to build inside or under a volcano as the magma moves slowly. The higher viscosity also means the magma can hold more gas.
What are the two types of magma and what makes them different?
I'm not sure... but the two different types of lava are: Viscous - sticky and slow moving, resulting in tall volcanoes Non Viscous - runny and fast moving, resulting in short and very spread out volcanoes (shield volcanoes)
What two important factors determine whether an eruption will be explosive or quiet?
The two important factors that determine whether an eruption will be explosive or quiet are the viscosity of the magma (how thick or sticky it is) and the presence of gases dissolved in the magma (such as water vapor and carbon dioxide). High viscosity and high gas content typically lead to explosive eruptions, while low viscosity and low gas content lead to quieter eruptions.
What are two types of magma?
The three types of magma are basalt, andesite, and rhyolite. Basalt is flowing and is usually around 1,200 degrees Celsius. Andesite is flowing and explosive and is usually between 800 to 1,000 degrees C. Rhyloite is very explosive and is usually at 750 to 850 degrees Celsius.
