Do shield volcanoes have high silica content in the lava?
No, shield volcanoes are characterized by lava with a low silica content. Consequently, the principal hazard of the volcano is the lava flow rather than the eruption itself.
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.
Which type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
How does silica affect the shape of a volcano?
A high silica content of the magma will form tall, steep-sided, or cone-shaped mountains. A low silica content produces shield shaped or broad volcanoes.

How are shield volcanoes and cinder cone volcanoes somewhat same?
Both erupt basaltic lava, which has a low silica content and a high temperature.
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.
Do shield volcanoes have high viscosity?
No. Shield volcanoes are fed by low-viscosity basaltic magma.

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.
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.
How does water affect volcanoes?
low water and low silica: the eruption is not that strong; low water and high silica: the magma comes out like a toothpaste coming out of its tube high water and low silica: the lava flows fast and strong. high water and high silica: lava is pasty and thick and flows strongly
