flows easily, so gas bubbles move up through it and escape fairly gently.
Shield volcanoes have low silica magma, which is more fluid and runny compared to magma with higher silica content. This low silica content contributes to the gentle, flowing eruptions characteristic of shield volcanoes.
low silica content (basaltic magma)
low silica content (basaltic magma)
Kilauea erupts low-silica lava.
Low silica magma typically flows easier than high silica magma because low silica magma has lower viscosity, meaning it is less resistant to flow. High silica magma is more viscous due to the presence of more silica tetrahedra in its composition, making it thicker and more difficult to flow.
no it has a generally low amount of silica.
Salt does not contain silica.
lava rich in silica
no. AA has a relatively low silica content level.
No. Kilauea erupts low-silica lava.
It determines high silica or low silica. It will determine if it is sticky or not, or if it flows fast or slow. *high in silica~Sticky, and slow. Will not flow easily. *low in silica~Fact, not sticky. Will flow easily.
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.
