If the temperature of the magma of a volcano is high and it contains low silica the lava flows?
If the temperature of the magma is high and it contains low silica, the lava will likely have a low viscosity, allowing it to flow more easily. This results in fluid lava flows that can travel long distances from the volcano. Such basaltic lava typically erupts gently, leading to the formation of broad, shield volcanoes rather than explosive eruptions. Overall, low-silica magma contributes to a more effusive volcanic activity.

What type of volcano has magma that contains large volumes of gases but not silica and water?
A volcano with magma that contains large volumes of gases but not silica and water is typically a shield volcano. These volcanoes have low viscosity magma that allows gases to escape easily, resulting in relatively gentle eruptions characterized by lava flows.
Is the lava from a shield volcano thick or thin?
silica content
Which magma contains small amounts of silica and has a low what?
Basaltic magma contains small amounts of silica and has a low viscosity, meaning it is relatively fluid and flows easily.
What type of lava does the bus-obo volcano have?
The Mayon Volcano in the Philippines typically has basaltic andesite lava flows, which are characterized by their high silica content and intermediate viscosity, allowing for slow-moving lava flows. This type of lava results in cone-shaped volcanoes with steep slopes.
What type of lava flows easily?
Basaltic lava flows easily due to its low viscosity, which is caused by its low silica content and high temperature. This type of lava can travel long distances and create smooth, gentle slopes as it cools.

Basaltic lava flows easily due to its low viscosity, which is caused by its low silica content and high temperature. This type of lava can travel long distances and create smooth, gentle slopes as it cools.
Does low silica mean shield volcano?
Yes, shield volcanoes are typically characterized by low silica magma, which has low viscosity and flows easily to create broad, gently sloping profiles. This type of volcano forms from repeated, non-explosive eruptions that result in layers of basaltic lava flows.
What is an eruption called when the magma is thin runny and contains very little silica?
An eruption with thin, runny magma containing very little silica is called an effusive eruption. This type of eruption usually results in lava flows that can travel long distances from the volcano.
Magma flows easily when it is low in?
silica content. High temperature and low silica content in magma allow for easier flow due to reduced viscosity. This type of magma often results in non-explosive volcanic eruptions with lava flows.
What kind of eruption is produced when basaltic lava that is low is silica flows from a volcano?
quiet nonexplosive eruptionsquiet nonexplosive eruptionsquiet nonexplosive eruptions
How does the amount of silica content change the viscosity of magma How does this affect the flow of magma?
The amount of silica and water affect the viscosity of the magma. The more viscous the magma, the slower the flow rate and the shorter and the thicker the flows. Silica makes for a more viscous magma.
What types of lava come from the San Cristobal volcano?
The San Cristobal volcano in Nicaragua primarily produces basaltic lava, which is low in silica content and flows easily. This type of lava typically results in effusive eruptions with lava flows that can travel long distances from the volcano. The lava from the San Cristobal volcano tends to be relatively fluid and forms shield volcanoes.
What is cause for some lava just to ooze out of the volcano?
Lava oozes out of a volcano primarily due to its low viscosity, which is influenced by its chemical composition and temperature. Basaltic magma, with its high temperature and low silica content, flows more easily, allowing it to escape from the volcano gradually. Additionally, the pressure buildup within the magma chamber can cause the magma to rise slowly, resulting in effusive eruptions where lava flows rather than explodes. This contrasts with more viscous magmas, which tend to trap gas and build pressure, leading to explosive eruptions.
