What type of volcano is most likely to form when magma is high in silica?
Lava high in silica (granitic lava) tends to be thick and viscous, so the volcano is likely to be composite rather than shield.
What percent of silica is in Mount Ruizs lava?
Mount Ruiz's lava typically contains around 60% to 70% silica. The exact percentage can vary depending on the specific type of eruption and the composition of the lava flow. This high silica content contributes to the lava's viscosity and the explosive nature of eruptions associated with the volcano.
Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
What type of lava flows the slowest?
Viscous lava, such as andesitic or rhyolitic lava, flows the slowest due to its high silica content. This type of lava tends to be thicker and more resistant to flow compared to basaltic lava, which is more fluid and flows more quickly.
What forms low silica lava?
Low silica lava, typically classified as basaltic lava, forms from the melting of mantle rocks, which have a low silica content. This type of lava has a low viscosity, allowing it to flow easily and travel long distances. It is commonly associated with shield volcanoes and mid-ocean ridges, resulting in broad, gently sloping landforms. The low silica content also leads to fewer explosive eruptions compared to high silica lavas.
What type of volcano is most likely to form when magma is high in silica?
Lava high in silica (granitic lava) tends to be thick and viscous, so the volcano is likely to be composite rather than shield.
What type of lava did Eyjafjallajökull produce?
Eyjafjallajökull volcano produced a type of lava called basaltic lava. Basaltic lava is low in silica content, which makes it less viscous and allows it to flow more easily over the surface, leading to the formation of shield volcanoes like Eyjafjallajökull.

Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
Which type of lava does mount Eyjafjallajokull have?
probably basaltic lava because the 2010 eruption was very explosive

What type of magma has a high silica content?
rhyolitic magma has a lot of silica and water vapors... thanks for asking answers.com ;)
What type of lava flows easily?
Basaltic lava flows easily due to its low viscosity, which is caused by its low silica content and high temperature. This type of lava can travel long distances and create smooth, gentle slopes as it cools.
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 type pf magma does mt Cleveland have?
Mt. Cleveland has felsic lava, high in silica.
What kind of volcano form from lava that is higher in water and silica content than lava that forms shield volcanoes?
Explosive stratovolcanoes form from lava that is higher in water and silica content than the lava that forms shield volcanoes. The high viscosity of this type of lava traps gases, leading to explosive eruptions that can eject ash, rock fragments, and lava at high speeds. This creates steep-sided volcanic cones with alternating layers of ash, lava, and volcanic rocks.
