What else can I help you with?
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.
Is scoria rich in silica?
Scoria typically contains high amounts of silica due to volcanic origins. It is formed from rapidly cooling lava with high viscosity, leading to the retention of silica in its composition.
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.
Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.
Was krakatau's erupted by lava rich in silica or lava low in silica?
lava rich in silica
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.
Shield volcanoes are almost entirely composed of this kind of very fluid lava.?
Basaltic lava (low in silica).
What type of magma does arenal have?
Ithink there is not different types of lava This answer is retarded because there is silica rich and silica poor magma^^ some people are not that smart
What kind of lava flows result from low water and low silica?
thin magma
Is scoria rich in silica?

What kind of volcano forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
cinder cone
What is basic lava?
Basic lava is the hottest lavas at about 10000 c and is highly fluid .it is dark coloured like basalt.rich in iron and mg but poor in silica

Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.
Does pillow lava have high silica?
No. Pillow lava is basaltic, so it has a low silica content.
