Silica content in strombolian eruptions is typically low (around 50-52%), as they are characterized by the eruption of basaltic magma. This type of magma has a lower silica content compared to other types such as andesitic or rhyolitic magmas, which are associated with different types of volcanic eruptions like explosive ones.

If you have quiet eruption what kind of silica do you have?
If an eruption is quiet, it typically indicates that the magma has low viscosity due to high silica content. The high silica content causes the magma to be more fluid, allowing gases to escape easily and resulting in a gentle eruption with less explosive activity.
What is the type of volcanic eruption that has high silica?

What is an eruption called when the magma is thin runny and contains very little silica?
An eruption with thin, runny magma containing very little silica is called an effusive eruption. This type of eruption usually results in lava flows that can travel long distances from the volcano.
How does magma composition and the resulting eruption affect the form of a volcano?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
What kind of eruption is produced when basaltic lava that is low in silica flows from a volcano?
A basaltic lava eruption that is low in silica tends to produce effusive eruptions. These eruptions are characterized by relatively gentle and steady flows of lava, rather than explosive eruptions with ash and pyroclastic material. Basaltic lava flows easily due to its low viscosity, allowing it to travel long distances before cooling.
What is the relationship between the silica contents of magma and the explosiveness of a volcanic eruption?
The high the silica content, the explosive and the eruption.
If you have quiet eruption what kind of silica do you have?
If an eruption is quiet, it typically indicates that the magma has low viscosity due to high silica content. The high silica content causes the magma to be more fluid, allowing gases to escape easily and resulting in a gentle eruption with less explosive activity.
What type of eruption produces a viscous magma containing 53 percent silica and a gas content of 2 percent?
A type of eruption that produces a viscous magma with 53 percent silica and a gas content of 2 percent is typically associated with a stratovolcano or a composite volcano. These eruptions are explosive due to the high viscosity of the magma, leading to the buildup of gas pressure before an explosive release. Example volcanoes with this type of eruption style include Mount St. Helens in the United States and Mount Pinatubo in the Philippines.
How can the composition of magma affect the way volcano erupts?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.

Magma that is low in silica generally produces what kind of eruption?
It produces a quiet eruption.

What is a mineral that effects the thickness of magama?
The more silica in lava, the more viscous the lava is. Silica (SiO2) content varies from 50 percent to 70 percent. Basaltic lava, which is 50 percent silica, is runny and contains relatively little gas. Granitic lava, typically around 70 percent silica, is 70 percent silica. It is much thicker and contains much more gas. As a result when granitic lava flows, it tends to release gasses (water and carbon dioxide) explosively. The lava on the Hawaiian Islands in basaltic, and flows easily. The lava in Mount St Helens is very thick, so when it finally reaches the surface it causes a much more violent and dangerous eruption.
