What else can I help you with?
Is rhyolite silica rich or silica poor?
Rhyolite is silica-rich, containing over 70% silica. It is an extrusive igneous rock with a fine-grained texture that forms from the rapid cooling of magma rich in silica content.
What kind of lava is silica poor?
Silica-poor lava is called mafic lava. It is low in silica content and high in iron and magnesium, which makes it less viscous and more fluid compared to silica-rich lava. Mafic lava typically erupts at higher temperatures and flows more rapidly, resulting in the formation of basaltic rocks.
What magma is rich in feldspars and silica?
no its the least silica rich of granitic and andesitic magma.
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 lava is extruded from Krakatoa?
Krakatoa is known to erupt basaltic lava, which is a type of lava low in silica content and therefore less viscous. This type of lava tends to flow more easily and create relatively gentle eruptions compared to more silica-rich and viscous lava types.
Is calcite silica rich or silica poor?
Calcite does not contain any silica. It is a carbonate mineral.
Is rhyolite silica rich or silica poor?
Rhyolite is silica-rich, containing over 70% silica. It is an extrusive igneous rock with a fine-grained texture that forms from the rapid cooling of magma rich in silica content.
Silica-rich magma erupts from the shield volcanoes giving them there broad flat shape?
False. The magma of shield volcanoes is silica-poor.
What kind of lava is silica poor?
Silica-poor lava is called mafic lava. It is low in silica content and high in iron and magnesium, which makes it less viscous and more fluid compared to silica-rich lava. Mafic lava typically erupts at higher temperatures and flows more rapidly, resulting in the formation of basaltic rocks.
What magma is rich in feldspars and silica?
no its the least silica rich of granitic and andesitic magma.
Would you expect a light gray igneous rock to be rich or poor in silica?
I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.
What type of magma does arenal have?
Ithink there is not different types of lava This answer is retarded because there is silica rich and silica poor magma^^ some people are not that smart
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.
Was krakatau's erupted by lava rich in silica or lava low in silica?
lava rich in silica
What type of lava is extruded from Krakatoa?
Krakatoa is known to erupt basaltic lava, which is a type of lava low in silica content and therefore less viscous. This type of lava tends to flow more easily and create relatively gentle eruptions compared to more silica-rich and viscous lava types.
Why are silica-rich magmas thicker than silica-poor magma?
The SiO4 tetrahedra continuously form bonds with adjacent ions and atoms, essentially causing the liquid to strik to itself.
What kind of silica do strato volcanos have?
silica-rich magma
