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.

Do basalt and rhyolite form magma?
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
Does lava turn to magma or magma turns to llava?
magma turns into lava.
Is andiestic magma high in silica?
Andesitic magma has intermediate silica content. Rhyolite has the highest(>68%) and Basaltic the least.
What does felsic magma make after its solid?
It will form granite if it cools underground and rhyolite if it cools at the surface.
Which kind of magma is more likely form a volcanic rock?
Rhyolitic magma, high in quartz and feldspar. Forms granite underground, rhyolite above ground.
Do basalt and rhyolite form magma?
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
Which rock takes a longer time to form rhyolite or granite?
Rhyolite cools faster from magma (lava) than does granite, which forms from slow cooling of magma deep underground. Granite.
What is an extrusive igneous rock?
Rhyolite
Does lava turn to magma or magma turns to llava?
magma turns into lava.
Is andiestic magma high in silica?
Andesitic magma has intermediate silica content. Rhyolite has the highest(>68%) and Basaltic the least.
How destructive is a volcano?
The volcano is destructive by the magma inside it. The substance called "rhyolite" or "sticky magma" that is filled has so much gas in it, it pushes up. Because the magma is sticky, the lava gets harder and harder to push up and basically turns into an explosive volcano. The magma seeps through towns, destroying buildings and killing people.
What are the magma types in order of decreasing viscosity?
Most viscous Felsic magma i.e. rhyolite Intermediate magma i.e. andersite Mafic magma i.e. Basalt Ultramafic magma i.e. Komatiite Least viscous
What does felsic magma make after its solid?
It will form granite if it cools underground and rhyolite if it cools at the surface.
When would rhyolite rock form?
Rhyolite refers to a pale fine-grained volcanic rock. It is formed when magma that would have formed granite managed to erupt onto the surface of the Earth.
What kind of rocks are formed when the magma cools on the earth's surface?
Extrusive igneous rocks such as basalt or rhyolite.
What is magma called after it hits the air and turns solid?
After magma hits air it turns into lava
Which kind of magma is more likely form a volcanic rock?
Rhyolitic magma, high in quartz and feldspar. Forms granite underground, rhyolite above ground.
