What else can I help you with?
Does pillow lava have high silica?
No. Pillow lava is basaltic, so it has a low silica content.
What type of lava does mt hood have high silica or low silica?
Mt. Hood has lava with high silica content, resulting in a more viscous and explosive eruption compared to lavas with lower silica content. High silica lava tends to form more explosive eruptions due to its increased resistance to flow.
Is kilauea high in silica?
No. Kilauea erupts low-silica lava.
What is the behavior of lava with silica content being high and low?
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.
How does the quartz in the lava effect it and how it erupts?
If lava contains quartz that means the silica content is high. A high silica content makes lava more viscous, and gives it the tendency to erupt explosively.
Does kilauea have a high or low silica content?
Kilauea erupts low-silica lava.
What kind of lava flows from Popocatepetl?
Popocat?petl produces a mixture of andesitic and dacite lava in the current cycle of activity. Andesitic, or Basaltic Andesite, is black volcanic rock that contains 55% silica. Dacite, on the other hand, is an igneous, volcanic rock that has a composition that is between Andesite and Rhyolite.
Is mount st Helens high in silica or low in silica?
Mount St Helens produces mostly dacite lava, which is relatively high in silica.
What kind of lava is silica poor?
Silica-poor lava is called mafic lava. It is low in silica content and high in iron and magnesium, which makes it less viscous and more fluid compared to silica-rich lava. Mafic lava typically erupts at higher temperatures and flows more rapidly, resulting in the formation of basaltic rocks.
Was krakatau's erupted by lava rich in silica or lava low in silica?
lava rich in silica
Is felsic lava thick?
Felsic lava is a slower moving lava, with high silica content. Most felsic lava deposits as granite, granite, muscovite, and orthoclase.
Material found in magma that formed from oxygen and silicon?
Silica yes! because when lava from the magma chamber rises toward the top of the volcano the lava or silica it depends on the hot ness of high silica or low silica!!!! :D
