lava rich in silica
silica content
no its the least silica rich of granitic and andesitic magma.
Thin, easy flowing lava is usually rich in iron and magnesium. Thick, slow moving lava is usually rich in silica.
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.
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
The lava is silica-rich, so it clogs in the vents. The pressure builds, and boom.
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.
Rhyolite is felsic and thus silica rich.
TThe magma is composed of gas and is silica rich.
silca rich
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.
== == 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.
