Which flows easier high silica magna or low silica magna?
High silica magma is more viscous (sticky) than low silica magma, so low silica magma lows easier.
What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
Does kilauea have a high or low silica content?
Kilauea erupts low-silica lava.
Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
Does the lava that forms shield volcanoes probably have a lot of silica or water in it?
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.

What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)
What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)
What is the average silica content of a'a lava?
A'a lava has a generally low silica content. Having low silica content means that it also has a low viscosity level. Having a low viscosity level means that it flows easily.
Does kilauea have a high or low silica content?
Kilauea erupts low-silica lava.
Which magma type resulted in a quiet eruptions?
That would normally be magma with a low silica content.
Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
Does the lava that forms shield volcanoes probably have a lot of silica or water in it?
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
Does pillow lava have high silica?
No. Pillow lava is basaltic, so it has a low silica content.
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.
An example of an igneous rock low in silica is granite?
False. Basalt would be an example of an igneous rock with a low silica content.
