Which is a cone-shaped hill or small mountain.

Compare and contrast the three types of magma?
Basaltic Magma is typically forms when rocks in the upper mantle melt...Andesitic Magma is found along continental margins....Rhyolitic Magma forms when molten material rises and mixes with the overlying silica-and water-richcontinental crust...All 3 of them is a magma.
Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
What does Magma that is rich in silica forms when the mantle mixes with?
Magma that is rich in silica forms when the mantle interacts with continental crust or when it undergoes partial melting of silica-rich rocks. This occurs because the addition of heat and pressure can cause the minerals in the crust to melt, leading to a higher concentration of silica in the resulting magma. This silica-rich magma tends to be more viscous and can lead to explosive volcanic eruptions when it rises to the surface.
Magma that is low in silica and produces nonexplosive eruptions is called?
Magma that is low in silica and produces nonexplosive eruptions is called basaltic magma. As basaltic magma has a low viscosity due to its low silica content, it tends to flow more easily, resulting in nonexplosive eruptions with lava flows.
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.
Magma that is low in silica and produces nonexplosive eruptions?
Low viscosity mafic magma.
Do silica-rich magma cause explosive eruptions?
yes
What causes the difference between quiet and exploses eruptions?
It depends on how much silica is in the magma. If there is low-silica in the magma then the volcano will erupt quietly. If there is high-silica in the magma then the volcano will erupt explosively.
Is mount Popocatepetl high in Silica?
Yes, Mount Popocatepetl is high in silica because it is a stratovolcano, which typically contains high amounts of silica in its magma composition. Silica-rich magma tends to be more viscous, leading to explosive eruptions as seen with the eruptions of Popocatepetl.
Which magma type resulted in a quiet eruptions?
That would normally be magma with a low silica content.
What element has the greatest effect on magma characteristics?
The silica content in magma has the greatest effect on its characteristics. High silica content makes magma more viscous and results in explosive volcanic eruptions, while low silica content produces runny magma and less explosive eruptions.
What are cinder cone magma chambers made up of?
