No. Kilauea erupts low-silica lava.
Kilauea erupts low-silica lava.
Because Mount Rainier is a Strato Volcano it has both quiet and explosive eruptions. Explosive(pyroclastic) flows have a high silica level. Quiet have low silica levels. The more silica the thicker the magma.
Mt. Etna is a stratovolcano like Krakatoa and Mt. Vesuvius, therefore it has a high silica content. Though lava with a high silica content does not tend to travel very far away from the source; it can be a double edged sword as magma with a high silica content tends to trap gasses until it reaches a bursting point, ending in a massive eruption.
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
Occasionally, yes. Most of Kilauea's eruptions are effusive, however.

Mount Hood has high silica levels so the lava is felsic (Mt. Hood's silica values are as high as 64%).
High silica magma is more viscous (sticky) than low silica magma, so low silica magma lows easier.
Salt does not contain silica.
low
no it has a generally low amount of silica.
Yes it is low in silica
