Low silica lava, typically classified as basaltic lava, forms from the melting of mantle rocks, which have a low silica content. This type of lava has a low viscosity, allowing it to flow easily and travel long distances. It is commonly associated with shield volcanoes and mid-ocean ridges, resulting in broad, gently sloping landforms. The low silica content also leads to fewer explosive eruptions compared to high silica lavas.
What else can I help you with?
Does the lava that forms shield volcanoes probably have a lot of silica or water in it?
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.
Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
What is the behavior of lava with silica content being high and low?
Lava with high silica content tends to be more viscous and flow more slowly, leading to explosive eruptions. In contrast, lava with low silica content is less viscous and flows more easily, resulting in gentler, effusive eruptions.
Does basilic lava have low silica?
Yes, basaltic lava has low silica content compared to other types of lava. Basaltic lava is typically rich in iron, magnesium, and calcium, which contribute to its low silica content. This low silica content also makes basaltic lava less viscous and more likely to flow easily.
Does the lava that forms shield volcanoes probably have a lot of silica or water in it?
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
Was krakatau's erupted by lava rich in silica or lava low in silica?
lava rich in silica
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.
Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
Does pillow lava have high silica?
No. Pillow lava is basaltic, so it has a low silica content.

Does kilauea have a high or low silica content?
Kilauea erupts low-silica lava.
Is kilauea high in silica?
No. Kilauea erupts low-silica lava.
What is the average silica content of a'a lava?
A'a lava has a generally low silica content. Having low silica content means that it also has a low viscosity level. Having a low viscosity level means that it flows easily.
Do shield volcanoes have high silica content in the lava?
No, shield volcanoes typically have low silica content in their lava, which results in fluid-like, runny eruptions. This low silica content allows for the lava to flow easily and create the wide, gentle slopes characteristic of shield volcanoes.
What kind of volcano forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
cinder cone
