Salt does not contain silica.
Kilauea erupts low-silica lava.
no it has a generally low amount of silica.
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. 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.
Mount Erebus has high silica content in its magma, which makes it more viscous and prone to explosive eruptions. This high silica content contributes to the formation of ash clouds and lava bombs during eruptions.
Mount St Helens produces mostly dacite lava, which is relatively high in silica.
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.
yes
No. Pillow lava is basaltic, so it has a low silica content.
it can be either low or high depending on source.
