Salt does not contain silica.
low
High silica magma is more viscous (sticky) than low silica magma, so low silica magma lows easier.
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
Shield volcanoes produce low-silica lava.
Kilauea erupts low-silica lava.
no it has a generally low amount of silica.
Yes it is low in silica
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.
low water and low silica: the eruption is not that strong; low water and high silica: the magma comes out like a toothpaste coming out of its tube high water and low silica: the lava flows fast and strong. high water and high silica: lava is pasty and thick and flows strongly
Mount Hood has high silica levels so the lava is felsic (Mt. Hood's silica values are as high as 64%).
Mount St Helens produces mostly dacite lava, which is relatively high in silica.
