Rhyolitic Magma | High in silica, Low temperature, explosive volcanoes. (Magma) |
Andesitic Magma | Less silica than R more than B, explosive/quiet eruptions. (Magma) |
Basaltic magma | Low silica, high temperature, quiet eruption. (Magma) |
High % silica | Explosive eruptions, occurs at subduction boundaries. |
Low % silica | Quiet eruptions, occurs at divergent boundaries & oceanic hot spots. |
Shield Volcanoes | Basaltic lava, low silica, high temperature, quiet eruption, formed at DIVERGENT boundaries/ oceanic hot spots. (Volcano) |
Cinder Cone | Made of solid pieces of pyroclastic material, Rhyolitic magma. (Volcano) |
Composite/Strato | Formed at subduction boundaries, Andesitic magma. (Volcano) |
Where do most Stratovolcanoes occur? | Pacific plate (ring of fire) at subduction boundaries. |
