What else can I help you with?
What kind of lava does Mount Etna have?
stratovolcano
What kind of eription is produced when basaltic lava that is low in silica flows from a volcan?
A quiet, non explosive eruption. Silica-high lava produces explosive eruptions.
What kind of eruption is produced when basaltic lava that is low is silica flows from a volcano?
quiet nonexplosive eruptionsquiet nonexplosive eruptionsquiet nonexplosive eruptions
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.
What kind of silica do strato volcanos have?
silica-rich magma
What kind of eruption is produced when basaltic lava that is low in silica flows from a volcano?
A basaltic lava eruption that is low in silica tends to produce effusive eruptions. These eruptions are characterized by relatively gentle and steady flows of lava, rather than explosive eruptions with ash and pyroclastic material. Basaltic lava flows easily due to its low viscosity, allowing it to travel long distances before cooling.
Why is the silica content of lava important?
The more silica crystal within the magma, the more viscous the magma is, because of crystals sticking together. So magma with low silica content is runny, and wiht just flow gently out of a volcano, like in hawai, but viscous (sticky, like honey) magma will not, and gas gets trapped within it, and then explodes out, cause large scale explosive erruptions.
What kind of springs form where pressurized water flows through cracks in cap rocks?
Artesian springs form where pressurized water flows through cracks in cap rock.
What kind of volcano forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
cinder cone
Silica and gypsum are what kind of minerals that are widely used in industry?
Gypsum is in Plaster and Silica is in silicone.
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.
When water flows away from points on earth what kind of tide is experienced?
I would think it would be low tide.
