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.

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 kilauea have a high or low silica content?
Kilauea erupts low-silica lava.
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.
Does mount erebus have high silica or low silica?
low
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 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 kilauea have a high or low silica content?
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.
How fast dose lava flow?
it all depends on the silica content which makes high or low viscosity
Does mount erebus have high silica or low silica?
low

Do shield volcanoes have high silica content in the lava?
No, shield volcanoes are characterized by lava with a low silica content. Consequently, the principal hazard of the volcano is the lava flow rather than the eruption itself.
