The more silica crystal within the magma, the more viscous the magma is, because of crystals sticking together.
So magma with low silica content is runny, and wiht just flow gently out of a volcano, like in hawai, but viscous (sticky, like honey) magma will not, and gas gets trapped within it, and then explodes out, cause large scale explosive erruptions.
no. AA has a relatively low silica content level.
Lava with high silica content tends to be more viscous and flow more slowly, leading to explosive eruptions. In contrast, lava with low silica content is less viscous and flows more easily, resulting in gentler, effusive eruptions.
Silica and oxygen content in lava affects its viscosity, which in turn impacts flow speed. Lava with higher silica content tends to be more viscous and flows slower, while lava with lower silica content flows faster. The presence of oxygen also influences lava's ability to flow by affecting its gas content and pressure.
Yes, basaltic lava has low silica content compared to other types of lava. Basaltic lava is typically rich in iron, magnesium, and calcium, which contribute to its low silica content. This low silica content also makes basaltic lava less viscous and more likely to flow easily.
No, shield volcanoes typically have low silica content in their lava, which results in fluid-like, runny eruptions. This low silica content allows for the lava to flow easily and create the wide, gentle slopes characteristic of shield volcanoes.

No. Pillow lava is basaltic, so it has a low silica content.

If lava contains quartz that means the silica content is high. A high silica content makes lava more viscous, and gives it the tendency to erupt explosively.
No, shield volcanoes typically have low silica content in their lava, which results in fluid-like, runny eruptions. This low silica content allows for the lava to flow easily and create the wide, gentle slopes characteristic of shield volcanoes.
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
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.
Kilauea erupts low-silica lava.
The opposite of basaltic is rhyolitic. Basaltic rocks are formed from lava that is low in silica content, while rhyolitic rocks are formed from lava that is high in silica content.
It has a low silica content.
