What Are The Three Factors That Influence Viscosity
Viscosity
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of "thickness". For example, honey has a much higher viscosity than water.
What are the factors of viscosity of lava?
The three factors that influence the viscosity of a lava are temperature, the dissolved gases it contains, and its chemical composition.
What factors influence viscosity?
CONCEPT: Viscosity: The state of being sticky, thick, and semi-fluid inconsistency, due to internal friction of fluids is called viscosity. The viscosity of a material is affected by temperature, pressure, nature of fluid, velocity gradient , etc.
What are the two major factors that influence the viscosity of magma lava?
The viscosity of magma depends upon its silica content and temperature.
What is viscosity and what factors influence the viscosity of magma?
Viscosity is a fluid's resistance to flow. Three factors that affect magma viscosity are temperature, composition, and presence of dissolved gases. Explain how the viscosity of magma influences the explosiveness of a volcano. More viscous magmas tend to generate more explosive eruptions.
What factors affect viscosity quizlet?
What are the four factors that affect viscosity? Temperature, Concentration, Attractive Forces, Particle Size.
What are the three main types of lava?
The high temperatures and pressure under Earth's crust keep magma in its fluid state. There are three basic types of magma: basaltic, andesitic, and rhyolitic, each of which has a different mineral composition. All types of magma have a significant percentage of silicon dioxide.
What factors control the viscosity of a melt?
Answer: Viscosity in a melt is controlled by its composition (specifically, silica content) and temperature. Temperature affects viscosity because heat causes chemical bonds to break more easily. Therefore, a hotter lava of a given composition is less viscous than a Page 2 cooler lava of the same composition.
What are the 3 processes of magma formation?
There are three principal ways rock behavior crosses to the right of the green solidus line to create molten magma: 1) decompression melting caused by lowering the pressure, 2) flux melting caused by adding volatiles (see more below), and 3) heat-induced melting caused by increasing the temperature.
What is viscosity and what factors influence the viscosity of magma How does viscosity affect the explosiveness of a volcano?
How does magma viscosity influence the explosive potential? A more viscous (thick) magma will produce a more violent eruption This is controlled in part by the concentration of silica in the magma. A magma with low silica (<45%) will be runny and so the eruption will not be explosive. …
