What is shield volcanoes lava composed of?
TThe magma is composed of gas and is silica rich.
Silica-rich magma erupts from the shield volcanoes giving them there broad flat shape?
False. The magma of shield volcanoes is silica-poor.
Is magma found on earthquakes or volcanoes?
Magma is generally associated with volcanoes
The magma of shield volcanoes is rich in?
The magma of shield volcanoes is rich in basalt. Basalt magma is low in viscosity and gas content, allowing it to flow easily and lead to the broad, gently sloping shape characteristic of shield volcanoes.
What liquid is in shield volcanoes?
Shield volcanoes may contain molten rock called magma, particularly of a basaltic composition.
Do shield volcanoes have high silica or low silica?
Shield volcanoes have low silica magma, which is more fluid and runny compared to magma with higher silica content. This low silica content contributes to the gentle, flowing eruptions characteristic of shield volcanoes.
What type of magma does surtsey have?
Surtsey has basaltic magma, which is associated with the eruption of shield volcanoes. This type of magma is characterized by its low silica content and fluidity, allowing it to flow easily to the surface and form lava flows.
What is in a shield volcanoes magma?
inside a shield volcano is a hot surface of mamga
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.
What is magma that has a low silica content called?
Magma with low silica content is called mafic magma. It is characterized by its high temperature, low viscosity, and dark-colored minerals like olivine and pyroxene. Mafic magma typically erupts from shield volcanoes and is associated with basaltic rocks.
Why are there different shaped volcanoes?
Different shaped volcanoes occur because of the way the magma flows. Three types of volcanoes are shield, composite, and caldera.
What type of magma is produced in the Kilauea?
Kilauea volcano typically produces tholeiitic basalt magma, which is low in silica content and flows easily. This type of magma is associated with shield volcanoes like Kilauea, known for their gentle eruptions and copious lava flows.
