silica poor
A quiet, non explosive eruption. Silica-high lava produces explosive eruptions.
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.
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.
Krakatau erupted lava that was rich in silica, as evidenced by its explosive eruption style, which is typically associated with higher silica content. High-silica lava tends to be more viscous, leading to pressure buildup and explosive volcanic activity, as seen in the 1883 eruption of Krakatau. If Table 1 indicates characteristics such as the eruption type or composition analysis supporting high viscosity or explosive behavior, this further supports the inference of silica-rich lava.
no. AA has a relatively low silica content level.
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
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.

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

Shield volcanoes are fed by basaltic magma.
