What else can I help you with?
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.
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.
Do shield volcanoes have a lot of silica or water?
Shield volcanoes have low silica content and low water content in their magma. This results in fluid lava flows that spread out over large distances, creating the characteristic broad, gently sloping shield shape.
What kind of rock is found in a shield volcano?
Shield volcanoes are primarily composed of basaltic rock, which is a type of volcanic rock that is low in silica content and high in iron and magnesium. This type of rock creates gently sloping shield volcanoes due to its low viscosity and ability to flow easily during eruptions.

How are shield volcanoes and cinder cone volcanoes somewhat same?
Both erupt basaltic lava, which has a low silica content and a high temperature.
Do shield volcanoes have high viscosity?
No, shield volcanoes have low viscosity lava due to their composition of basaltic magma, which has low silica content. This low viscosity allows the lava to flow easily and spread out over a wide area, resulting in the gentle, sloping shape characteristic of shield volcanoes.

Wide gently sloping mountains formed by low-silica lava flows are called?
shield volcanoes
What type of volcano is characterized by low silica magma and relatively nonviolent eruptions?
flood basalt, lava dome, and shield volcanoes do.
Which type of magma causes quiet volcanoes?
Mafic magma (low in silica content) typically causes quiet eruptions because it is less viscous and flows more easily, leading to gentle lava flows. These eruptions are characterized by low explosivity and can result in shield volcanoes or lava plateaus.
Shield volcanoes are almost entirely composed of this kind of very fluid lava.?
Basaltic lava (low in silica).
Do composite volcanoes have high or low silica?
Composite volcanoes are often associated with moderate to high silica contestant, though in reality, the magma composition will vary over time.
