What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
Does mt.st.helens have a high or low silica content?
Because Mount Rainier is a Strato Volcano it has both quiet and explosive eruptions. Explosive(pyroclastic) flows have a high silica level. Quiet have low silica levels. The more silica the thicker the magma.
Does Hawaii experience effusive or explosive eruptions?
Occasionally, yes. Most of Kilauea's eruptions are effusive, however.
What is the silica content of magma?
Mt. Etna is a stratovolcano like Krakatoa and Mt. Vesuvius, therefore it has a high silica content. Though lava with a high silica content does not tend to travel very far away from the source; it can be a double edged sword as magma with a high silica content tends to trap gasses until it reaches a bursting point, ending in a massive eruption.
What is a low-silica magma?
A magma containing not much silica (= SiO2). For example: a basaltic magma. These magma's have a low viscosity since the lower the SiO2-content, the lower the viscosity; and hence flow easily (↔ a felsic magma).
Is kilauea high in silica?
No. Kilauea erupts low-silica lava.

Does pillow lava have high silica?
No. Pillow lava is basaltic, so it has a low silica content.
What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)
What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)
How does silica content affect igenous rocks?
It determines high silica or low silica. It will determine if it is sticky or not, or if it flows fast or slow. *high in silica~Sticky, and slow. Will not flow easily. *low in silica~Fact, not sticky. Will flow easily.

What is the average silica content of a'a lava?
A'a lava has a generally low silica content. Having low silica content means that it also has a low viscosity level. Having a low viscosity level means that it flows easily.
How does silica affect the shape of a volcano?
A high silica content of the magma will form tall, steep-sided, or cone-shaped mountains. A low silica content produces shield shaped or broad volcanoes.
