Mount Cleveland, a stratovolcano in Alaska, typically has a high silica content in its volcanic rocks, which is common for volcanoes in the Aleutian arc. The specific silica content can vary depending on the eruption. The water content in Mount Cleveland's magma is also high, contributing to its explosive eruptions.

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 is the silica content of magma?
The silica content of magma typically ranges from about 40% to 75%. Magma with higher silica content tends to be more viscous and explosive, while magma with lower silica content is typically more fluid and less explosive.
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.
What is a low-silica magma?
A low-silica magma has a lower concentration of silica oxide compared to high-silica magmas. This type of magma is typically associated with basaltic or mafic compositions, which have higher temperatures and lower viscosity, allowing for easier flow and the formation of shield volcanoes.
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 type pf magma does mt Cleveland have?
Mount Cleveland in Alaska is known to have andesitic magma, which is a type of magma with intermediate silica content. This type of magma typically leads to explosive eruptions.
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 is the silica content of magma?
The silica content of magma typically ranges from about 40% to 75%. Magma with higher silica content tends to be more viscous and explosive, while magma with lower silica content is typically more fluid and less explosive.
What is a volcano with high silica?
A volcano with high silica content is referred to as a stratovolcano or composite volcano. These volcanoes have highly viscous magma due to the high silica content, leading to explosive eruptions that can be violent and dangerous. Examples include Mt. St. Helens in the United States and Mt. Fuji in Japan.
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.
What is a low-silica magma?
A low-silica magma has a lower concentration of silica oxide compared to high-silica magmas. This type of magma is typically associated with basaltic or mafic compositions, which have higher temperatures and lower viscosity, allowing for easier flow and the formation of shield volcanoes.
How are silica and water related to volcanos explosiveness?

What is the type of magma Mt fuji has?
Scientists have identified distinct phases of volcanic activity in the formation of Mt. Fuji. The first phase is composed of an andesite which forms the deep core of the volcano and this is covered by later basalt lavas.
Where is the Mt Pleasant Branch Library in Cleveland located?
The address of the Mt Pleasant Branch Library is: 14000 Kinsman Rd., Cleveland, 44120 4823
What made mt st Helens so explosive?
Mount Saint Helens' magma/lava composition is different to many volcanoes and is about 64%silica and 4% water.
