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.
How do you think the location of a volcano affects the magma composition?
The location of a volcano can affect the magma composition by influencing the source of the magma. Magma composition can vary based on factors like the depth of the magma source, the presence of subducted materials, and the amount of water and gases present. Different locations can have different geological conditions that influence the composition of the magma erupted by a volcano.
What is Sunset Crater's magma composition?
Sunset Crater was fed by basaltic magma.
What magma composition does Mt Hekla have?
Mt. Hekla in Iceland has a composition of intermediate to felsic magma, which is rich in silica, giving it a higher viscosity compared to basaltic magma. This type of magma can lead to explosive eruptions.
3 ways composition of magma can be modified?
The composition of magma can be modified by the addition of new material, such as when magma assimilates surrounding rock as it rises to the surface. Magma composition can also be altered through fractional crystallization, where minerals crystallize and separate from the remaining melt. Mixing of different magma batches can further modify composition through hybridization.

How much magma could Popocatepetl hold?
Alot

Sunset Crater was fed by basaltic magma.
Why is magma not a mineral?
Magma is not a mineral becauseIt is liquid.It does not have a definite chemical composition.
What type of magma is closer to intrusive rocks?
magma can be classified into two,magma of granitic composition(originates from lower continental crust) and magma of basaltic composition (which originates from upper mantle).Both can form intrusive rocks.

What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
The average composition of rocks comprising a large composite cone or stratovolcano is similar to what magma?
The average composition of rocks in a large composite cone or stratovolcano is similar to andesitic magma. Andesitic magma is intermediate in composition between basaltic and rhyolitic magma, containing elements such as silica, magnesium, and iron. This magma type is responsible for the explosive eruptions characteristic of stratovolcanoes.
