Thinner easy flowing lavas are rich in?
Thinner, easy-flowing lavas are rich in silica (SiO2) and have low viscosity. This type of lava is typically associated with shield volcanoes and effusive eruptions.
Is the composition of the hawaiian lavas felsic or mafic?
The composition of Hawaiian lavas is typically mafic, as they are rich in magnesium and iron and have a lower silica content. This composition gives them low viscosity and allows them to flow easily.
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 is Krakatoa a silica rich or a silica poor?
Krakatoa is silica-rich, meaning it contains a high amount of silicon dioxide (silica) in its composition. This high silica content is associated with explosive volcanic eruptions due to the interaction between silica and magma.
What magma is rich in feldspars and silica?
no its the least silica rich of granitic and andesitic magma.
