Eruptions characterized by high silica content are typically explosive and are known as silicic or rhyolitic eruptions. The high viscosity of silica-rich magma traps gases, leading to increased pressure and violent eruptions. This type of eruption can produce pyroclastic flows, ash clouds, and volcanic domes, contrasting with the more effusive eruptions associated with low-silica basaltic magma.

What is the type of volcanic eruption that has high silica?
Crazy
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.
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 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.
In a strombolian eruption the percent of silica changes?
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.

What properties of magma help determine the type of eruption?
The properties of magma that help to determine the type of eruption are the magma's viscosity and its silica content. Those volcanoes that exhibit massive eruptions have a high viscosity and high silica content.
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.

How are volcanic eruptions affected by the type of lava?
The more silaceous the lava, (higher silica content), the more explosive the eruption.
What do lava flow made of pahoehoe and AA indicate about the type of volcanic eruptions that occured?
It was a quiet eruption and it was low in silica
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.
Infer which kind of lava Krakatau erupted and mdash lava rich in silica or lava low in silica. Support your inference using data in Table 1.?
Krakatau erupted lava that was rich in silica, as evidenced by its explosive eruption style, which is typically associated with higher silica content. High-silica lava tends to be more viscous, leading to pressure buildup and explosive volcanic activity, as seen in the 1883 eruption of Krakatau. If Table 1 indicates characteristics such as the eruption type or composition analysis supporting high viscosity or explosive behavior, this further supports the inference of silica-rich lava.
Magma that is low in silica generally produces what kind of eruption?
It produces a quiet eruption.
