Is the lava from a shield volcano thick or thin?
silica content
What magma is rich in feldspars and silica?
no its the least silica rich of granitic and andesitic magma.
Thinner easy flowing lavas are rich in?
Thin, easy flowing lava is usually rich in iron and magnesium. Thick, slow moving lava is usually rich in silica.
What turns magma into rhyolite?
Rhyolite is a volcanic rock formed when highly viscous magma rich in silica erupts. In many cases rhyolite comes in the form of tuff, formed when the material is blasted out explosively, forming ash and pumice which eventually settle to the ground. Sometimes this tuff is so hot it gets welded into a solid rock. In other cases it erupts as lava. This lava will either form extremely thick lava flows or pile up on the vent as a lava dome.
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
What causes volcanic eruptions for composite volcanoes?
The lava is silica-rich, so it clogs in the vents. The pressure builds, and boom.
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.
Is rhyolite silica rich or silica poor?
Rhyolite is felsic and thus silica rich.
What is shield volcanoes lava composed of?
TThe magma is composed of gas and is silica rich.
What is Krakatoa a silica rich or a silica poor?
silca rich
How does lava turn into basalt?
Basalt is a type of volcanic erock. It forms when lava that is low in silica and rich in iron and magnesium cools and hardens at or above Earth's surface, most often in the form of lava flows.
Where does felsic lava form at?
== == Felsic lava has a higher silica content than mafic lava. Felsic lava is slower moving (high viscosity) than the less viscous mafic lava. Mafic lava is higher in dark minerals and higher in the elements iron and magnesium.
