silica poor
A quiet, non explosive eruption. Silica-high lava produces explosive eruptions.
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.
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.
no. AA has a relatively low silica content level.
Shield volcanoes are fed by basaltic magma.
lava rich in silica

Basaltic lava (low in silica).
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
thin magma

cinder cone
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

No. Pillow lava is basaltic, so it has a low silica content.
