The two main factors that affect viscosity are temperature and silica content. Higher temperatures lower viscosity while higher silica content increases 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.
Pressure and temperature are the two factors that affect flow and viscosity. Viscosity refers to the resistance of a liquid to the shear forces.
Higher silicon content in magma leads to higher viscosity. This is because silicon tetrahedra form polymerized chains that hinder flow, making the magma more viscous. Lower silica content results in lower viscosity magma.
Blood viscosity is measured by a test called a viscometer, which determines how easily blood flows. Factors that can affect blood viscosity include temperature, hematocrit levels, and the presence of certain proteins or diseases.
Magmas with high viscosity and gas content tend to produce violent volcanic eruptions. High viscosity magmas are thicker and have more difficulty releasing gas, leading to pressure build-up and explosive eruptions. This often occurs with felsic or rhyolitic magmas.
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.
All of these factors affect the viscosity of magma. The amount of gases can influence the fluidity, while the silica content directly impacts thickness, and temperature affects the overall mobility of the magma. Therefore, none of these factors can be excluded as they all play a role in determining viscosity.

The silica content. A higher silica content results in a more viscous magma.
Factors that affect a fluid's viscosity include temperature (higher temperatures lead to lower viscosity), pressure (increased pressure can increase viscosity), and the composition of the fluid (molecular size and shape can affect how easily molecules can flow past each other).
Granitic magmas are thicker than basaltic magmas because they have higher silica content, which increases viscosity. The higher silica content leads to stronger bonding between the silica tetrahedra, making it more difficult for the magma to flow. Basaltic magmas, on the other hand, have lower silica content and are less viscous, allowing them to flow more easily.
The explosive potential of magma depends more on viscosity gas content than on temperature. Most magmas are at temperature of at least 700 degrees Celcius. Interestingly, the most explosive magmas are the high-silica magmas, which have lower melting temperatures.
