Mount Hood has high silica levels so the lava is felsic (Mt. Hood's silica values are as high as 64%).

What type of volcano is most likely to form when magma is high in silica?
Lava high in silica (granitic lava) tends to be thick and viscous, so the volcano is likely to be composite rather than shield.
What is the type of lava in the composite volcanoes?
Most composite volcanoes are comprised of Andesitic lava. Andesetic lava has an intermediate silica content compared to granitic with a high silica content and basaltic with a low silica content.
What type of magma has a high silica content?
rhyolitic magma has a lot of silica and water vapors... thanks for asking answers.com ;)
How are volcanic eruptions affected by the type of lava?
The more silaceous the lava, (higher silica content), the more explosive the eruption.
What type of lava flows easily?
Basaltic lava has a low viscosity which means it is thin and runny so it flows easily and spreads out.(:
What type of lava did Eyjafjallajökull produce?
It had high silica lava, or AA lava.

Mt. Cleveland has felsic lava, high in silica.

How are volcanic eruptions affected by the type of lava?
The more silaceous the lava, (higher silica content), the more explosive the eruption.
Which type of lave is better for forming lava tube caves?
"Basic", or low-silica, basalt lava, as its viscosity is relatively low.
What type of lava flows easily?
Basaltic lava has a low viscosity which means it is thin and runny so it flows easily and spreads out.(:
How does silica affect the type of explosion a vocano will have?
When lava flows through a patch of silica it become thick. When the thick lava hits water, it boils the water and traps the gasses. These gasses make a violent Explosion.
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 type of lava does Hekla in Iceland have?
Basic, or low-silica. It's essentially basalt.
What type of material do explosive volcanoes produce?
An explosive eruption is caused by magma with a high content of water and silica. Non-explosive eruptions are caused by either lava because it is a thicker consistency, or magma with a low content of water and silica.
