What is the most abundant compound found in magma?
The most abundant compound found in magma is silica (SiO2), which is commonly found in the form of quartz and feldspar minerals. Silica content plays a key role in determining the viscosity and behavior of magma.
Which is the most abundant in magma and has the greatest effect on its characteristics?
Silica is the most abundant component in magma and has the greatest effect on its characteristics. The amount of silica present determines the magma's viscosity, which in turn influences the explosiveness of volcanic eruptions.
What do both silica and water do to magma?
Silica is silicon dioxide. Is is perhaps the most common compound on earth. In magma the amount of silica is key in determining the viscosity. More silica leads to a more viscous magma.
What is a low-silica magma?
A low-silica magma has a lower concentration of silica oxide compared to high-silica magmas. This type of magma is typically associated with basaltic or mafic compositions, which have higher temperatures and lower viscosity, allowing for easier flow and the formation of shield volcanoes.
Which flows easier high silica magna or low silica magna?
Low silica magma typically flows easier than high silica magma because low silica magma has lower viscosity, meaning it is less resistant to flow. High silica magma is more viscous due to the presence of more silica tetrahedra in its composition, making it thicker and more difficult to flow.
Is Silica is the most abundant compound found in magma?
Silica is the most abundant compound found in magma. In the earth's crust, oxygen and silicon are the abundant elements which form the compound known as silica.

Material found in magma that formed from oxygen and silicon?
Silica yes! because when lava from the magma chamber rises toward the top of the volcano the lava or silica it depends on the hot ness of high silica or low silica!!!! :D

What is the silica content of basaltic magma?
The two most abundant elements in earth's crust and mantle are oxygen and silicon. These two elements combine to form the molecule called silica the basaltic magma. Basaltic magmas that form the oceanic crust of the Earth are generated in the asthenosphere at a depth of about 70 kilometres. Silica forms 50% of the basaltic magma.
Does basaltic magma have a lot of silica or very little?
Basaltic magma has relatively low silica content compared to other types of magma. It is typically around 45-52% silica.
Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the silica content.
What mineral that affects magma thickness?
The mineral that affects magma thickness is silica. Magma with high silica content tends to be more viscous, resulting in thicker magma. Conversely, magma with low silica content is less viscous and flows more easily.
What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)
