What is Krakatoa a silica rich or a silica poor?
silca rich
Does rhyolite or basalt have more silica in it?
rhyolite
Is scoria rich in silica?
No. Scoria is relatively silica poor.
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 magma is rich in feldspars and silica?
no its the least silica rich of granitic and andesitic magma.
Is rhyolite an polymerization sedimentary rock?
No, rhyolite is a silica-rich volcanic or igneous rock.
What is Krakatoa a silica rich or a silica poor?
silca rich
Does rhyolite or basalt have more silica in it?
rhyolite
Is scoria rich in silica?
No. Scoria is relatively silica poor.
Is calcite silica rich or silica poor?
Calcite does not contain any silica. It is a carbonate mineral.
Would you expect a light gray igneous rock to be rich or poor in silica?
rich
Is rhyolite a basaltic composition?
No. Basalt is a low-silica igneous rock while rhyolite is high-silica. As far as volcanic rocks go, they are essentially opposites.

Which rock is most felsic out of rhyolite andesite and basalt?
Of these Rhyolite has the highest silica content.
Why is rhyolite felsic?
Rhyolite contains abundant silica and alkali feldspar, which are the the defining components of felsic rock.
What kind of lava does composite volcanoes produce AA or pahoehoe?
Usually neither. A'a and pahoehoe lavas are both of mafic composition (rich in iron and magnesium, poor in silica) and form basalt when they cool. Composite volcanoes usually erupt material of intermediate to felsic composition (felsic is rich in alkalis, aluminum, and silica), with lavas cooling into rocks such as andesite, dacite, and rhyolite.
What is the name of a volcanic rock with high silica content?
Rhyolite.
