What else can I help you with?
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 mount erebus have high silica or low silica?
Mount Erebus has high silica content in its magma, which makes it more viscous and prone to explosive eruptions. This high silica content contributes to the formation of ash clouds and lava bombs during eruptions.
Low or high viscosity in mount saint Helen's?
The magma beneath Mount St. Helens is typically of low viscosity due to its composition, which is rich in silica and gas. This low viscosity magma allows for gases to escape easily, resulting in explosive eruptions.
Does Mount Shasta have high silica?
Yes, Mount Shasta has high silica content in its volcanic rocks. Silica-rich magma is one of the reasons for the explosive nature of some volcanic eruptions in the region.
What type of lava does mt hood have high silica or low silica?
Mt. Hood has lava with high silica content, resulting in a more viscous and explosive eruption compared to lavas with lower silica content. High silica lava tends to form more explosive eruptions due to its increased resistance to flow.

What type of lava does mt hood have high silica or low silica?
Mt. Hood has lava with high silica content, resulting in a more viscous and explosive eruption compared to lavas with lower silica content. High silica lava tends to form more explosive eruptions due to its increased resistance to flow.
Does kilauea have a high or low silica content?
Kilauea erupts low-silica lava.
Does AAA have high silica?
no it has a generally low amount of silica.
Is salt high or low in silica?
Salt does not contain silica.
Which flows easier high silica magna or low silica magna?
Low silica magma typically flows easier than high silica magma because low silica magma has lower viscosity, meaning it is less resistant to flow. High silica magma is more viscous due to the presence of more silica tetrahedra in its composition, making it thicker and more difficult to flow.
Is kilauea high in silica?
No. Kilauea erupts low-silica lava.
What type of volano is Mount St Helens a shield or composite?
Mount St. Helens is a composite volcano, also known as a stratovolcano. It is characterized by its steep sides and explosive eruptions caused by the high silica content of its lava. Shield volcanoes, on the other hand, have gentle slopes and are built from successive lava flows with low viscosity.
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.
