What magma is silica-rich thick magma?
An acid magma or a granitic magma.
What kind of silica do strato volcanos have?
silica-rich magma
What are silica rich and thick magma is what?
Silica is sand dust.
What is Silica rich thick magma called?
Silica-rich thick magma is called rhyolite. It contains high levels of silica, making it very viscous and typically light in color. Rhyolite is associated with explosive volcanic activity due to the build-up of pressure caused by the slow movement of its thick lava.
What type of magma produces violent reaction?
Acidic lava is very viscous, and thus will harden and block the vent. The magma will force its way out through the vent and create a violent explosion.
What effect does silica content have on the charactersitics of magma?
The silica can make the magma flow slower and also can make the magma's color lighter.
Is granitic magma very silica-rich.?
Yes
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 term is used to desribe magma that is rich in feldspars and silica?
energy
Do silica-rich magma cause explosive eruptions?
yes
Silica-rich magma erupts from the shield volcanoes giving them there broad flat shape?
False. The magma of shield volcanoes is silica-poor.
How does the silica content of molten material effects the color of igneous rock?
Silica in molten material tends to crystallise as quartz, which is white or mostly pale in colour. So felsic rocks (from silica-rich magma) tend to be pale, while mafic rocks (from silica-poor magma) tend to be dark in colour.
