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.
A magma's viscosity is directly related to its temperature and silica content. Higher temperatures and lower silica content result in lower viscosity, making the magma more fluid and able to flow more easily.
While height can influence the explosivity of a volcano to some extent, it is not the sole determining factor. The composition of magma, the presence of gas and water, and the type of eruption (effusive vs explosive) also play crucial roles in determining a volcano's explosive power. Additionally, factors such as viscosity of magma and volatility of gases can further impact volcanic explosivity.
No. Ultramafic magma would have a low viscosity.

silica content
A magma's viscosity is directly related to its temperature and silica content. Higher temperature and lower silica content typically result in lower viscosity, making the magma more fluid and runny. Conversely, lower temperature and higher silica content lead to higher viscosity, resulting in a thicker, more sticky magma.

The amount of dissolved gas in magma can influence its viscosity and explosivity. Higher gas content can lead to more explosive eruptions as the gas expands and tries to escape. Lower gas content can result in less explosive lava flows.
Silica is the mineral that determines magma viscosity. Magma with high silica content tends to be more viscous, leading to slower flow and potentially more explosive volcanic eruptions.
Magma with low viscosity
The silica content. A higher silica content results in a more viscous magma.
Viscosity in magma refers to its resistance to flow. Magma with high viscosity is thick and sticky, flowing slowly, while magma with low viscosity is more runny and flows more easily. Viscosity is influenced by factors like temperature, silica content, and gas content in the magma.
Differences in magma composition, such as viscosity and gas content, can affect the explosivity of a volcanic eruption. Magma with high viscosity tends to trap gas bubbles, leading to more explosive eruptions, while low-viscosity magma tends to flow more easily and result in gentler eruptions. Additionally, variations in gas content can influence the violence of an eruption by affecting the build-up of pressure within the magma chamber.
