What volcano forms from lava that contains relatively small amounts of gases and silica?
A volcano that forms from lava containing relatively small amounts of gases and silica is typically a shield volcano. These volcanoes have broad, gently sloping sides and are primarily built up by the flow of low-viscosity basaltic lava, which can travel long distances. The low gas content allows for less explosive eruptions, resulting in relatively calm lava flows. Examples include Mauna Loa and Kilauea in Hawaii.
What else can I help you with?
Which magma contains small amounts of silica and has a low what?
Basaltic magma contains small amounts of silica and has a low viscosity, meaning it is relatively fluid and flows easily.
Is scoria rich in silica?
Scoria typically contains high amounts of silica due to volcanic origins. It is formed from rapidly cooling lava with high viscosity, leading to the retention of silica in its composition.
What type of volcano has magma that contains large volumes of gases but not silica and water?
A volcano with magma that contains large volumes of gases but not silica and water is typically a shield volcano. These volcanoes have low viscosity magma that allows gases to escape easily, resulting in relatively gentle eruptions characterized by lava flows.
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 is in a composite volcano?
A composite volcano has high silica because they are known to be explosive.
Which magma contains small amounts of silica and has a low what?
Basaltic magma contains small amounts of silica and has a low viscosity, meaning it is relatively fluid and flows easily.

What type of volcano will form from a small volcano erupting with high amounts of silica?

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.
How much silica is in a composite volcano?
A composite volcano has high silica because they are known to be explosive.
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.
What type of volcano is characterized by low silica magma and relatively nonviolent eruptions?
flood basalt, lava dome, and shield volcanoes do.
What is the shape of a volcano with low silica?
Shield Volcano
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
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.
