What kind of eruption is produced when basaltic lava that is low in silica flows from a volcano?
A basaltic lava eruption that is low in silica tends to produce effusive eruptions. These eruptions are characterized by relatively gentle and steady flows of lava, rather than explosive eruptions with ash and pyroclastic material. Basaltic lava flows easily due to its low viscosity, allowing it to travel long distances before cooling.
The type of magma that often produces a violent eruptions can be described?
Thick due to high silica content.
What kind of eription is produced when basaltic lava that is low in silica flows from a volcan?
A quiet, non explosive eruption. Silica-high lava produces explosive eruptions.
What element has the greatest effect on magma characteristics?
The silica content in magma has the greatest effect on its characteristics. High silica content makes magma more viscous and results in explosive volcanic eruptions, while low silica content produces runny magma and less explosive eruptions.
Magma that is low in silica and produces nonexplosive eruptions?
Low viscosity mafic magma.

Why do volcanic eruptions differ?
The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.
What element has the greatest effect on magma characteristics?
The silica content in magma has the greatest effect on its characteristics. High silica content makes magma more viscous and results in explosive volcanic eruptions, while low silica content produces runny magma and less explosive eruptions.
Describe how differences in magma affect volcanic eruptions?
It depends on the texture of the magma, if it is thick then it won't let the gases escape, and if it is liquidy then the gases will escape resulting in a nonexplosive eruption. If the magma is high in silica and water then it will be thick If the magma is low or has no silica or water then it will be liquidy. - Negehna 6th Grade
Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
Is mount Popocatepetl high in Silica?
Yes, Mount Popocatepetl is high in silica because it is a stratovolcano, which typically contains high amounts of silica in its magma composition. Silica-rich magma tends to be more viscous, leading to explosive eruptions as seen with the eruptions of Popocatepetl.
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.
What type of magma produces pahoehoe?
Magma that is low in silica flows readily and produces dark-colored lava. Therefore magma that is low in silica produces Pahoehoe lava. This is called mafic or basaltic magma.
