What is silica content of a cinder cone volcano?
The silica content of the lava from a cinder cone volcano is typically low to moderate. This type of volcano erupts basaltic to andesitic lava, which contains lower silica levels compared to other types of volcanoes like stratovolcanoes.
What conditions make for a violent volcano eruptions?
magma and high silica content
What relationship appears to exisit between the silica and the water content of the magma and the type of volcano that it produced?
The relationship between silica content and water content in magma significantly influences the type of volcano formed. Magmas with high silica and water content tend to produce explosive, stratovolcanoes, as their viscosity traps gases, leading to violent eruptions. Conversely, low-silica, low-water magmas result in less viscous flows, creating shield volcanoes that produce gentle eruptions. This relationship emphasizes the role of magma composition in determining volcanic behavior and morphology.
How much silica is in a composite volcano?
A composite volcano has high silica because they are known to be explosive.
What does silica content?
Any metrial or thing which containts silica in it is call silica content..
What is silica content of a cinder cone volcano?
The silica content of the lava from a cinder cone volcano is typically low to moderate. This type of volcano erupts basaltic to andesitic lava, which contains lower silica levels compared to other types of volcanoes like stratovolcanoes.
How much silica does a composite volcano have?
The silica content will vary from one volcano to the next and will even vary over time for a single volcano. On average, though, composite volcanoes erupt intermediate rocks that are 52-63% silica.
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.
What two properties of magma determine what kind of volcano will form?
The silica content and the gas content of magma are two properties that determine what kind of volcano will form. Magma with low silica content and low gas content tends to form effusive, shield volcanoes, while magma with high silica content and high gas content tends to form explosive, stratovolcanoes.
What conditions make for a violent volcano eruptions?
magma and high silica content
What is the relationship between silica or water content of magma and materials ejected from an volcano?
The concentration of silica and water content in magma influence the force with which it is ejected from a volcano. The higher the levels of water and other gasses as well as the more silica it contains, the more explosive the eruption will be.
What does silica content?
Any metrial or thing which containts silica in it is call silica content..
What type of magma does cotopaxi have?
blue the cotopaxi volcano has red magma when turned to rock. it also has a high silica content
How much silica is in a composite volcano?
A composite volcano has high silica because they are known to be explosive.
Do shield volcanoes have high silica content in the lava?
No, shield volcanoes typically have low silica content in their lava, which results in fluid-like, runny eruptions. This low silica content allows for the lava to flow easily and create the wide, gentle slopes characteristic of shield volcanoes.
Suppose a volcano that is about to erupt contains mafic magma. The mafic magma has a very low silica content. what types of igneous rocks will the volcano most likely form?
basalt
What does the amount of silica in a volcanos magma determine about its eruption?
If a volcano's magma is high in silica, the volcano will probably erupt explosively. If the magma is not high in silica, the volcano will probably erupt quietly.
