Was krakatau's erupted by lava rich in silica or lava low in silica?
lava rich in silica
How much silica does mafic lava have?
Less than 45%
Does AAA have high silica?
no it has a generally low amount of silica.
What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
Does pillow lava have high silica?
No. Pillow lava is basaltic, so it has a low silica content.
What kind of lava is silica poor?
silica poor
What is a mineral that effects the thickness of magama?
The more silica in lava, the more viscous the lava is. Silica (SiO2) content varies from 50 percent to 70 percent. Basaltic lava, which is 50 percent silica, is runny and contains relatively little gas. Granitic lava, typically around 70 percent silica, is 70 percent silica. It is much thicker and contains much more gas. As a result when granitic lava flows, it tends to release gasses (water and carbon dioxide) explosively. The lava on the Hawaiian Islands in basaltic, and flows easily. The lava in Mount St Helens is very thick, so when it finally reaches the surface it causes a much more violent and dangerous eruption.
Lava that is low in silica tends to?
Lava that is low in silica tends to have lighter rocks come out of it.
What is the importance of a silica and oxygen in lava flow speed?
Silica will determine if the lava is hot and runny or thick and slow!
What type of lava did Eyjafjallajökull produce?
It had high silica lava, or AA lava.
What type of lava does mt hood have high silica or low silica?
Mount Hood has high silica levels so the lava is felsic (Mt. Hood's silica values are as high as 64%).
Is kilauea high in silica?
No. Kilauea erupts low-silica lava.
