What are the three main types of magma what factor determines these classifications?
The three main types of magma are basaltic magma, andesitic magma, and rhyolitic magma. They are classified according to their mineral composition. Basaltic magma is composed of SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na. Andesitic magma is composed of SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K. Rhyolitic magma is composed of SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na.
What are magmas classified under?
Magmas are classified based on their silica content, which determines their viscosity and behavior. They can be classified as basaltic, andesitic, or rhyolitic, with variations in composition such as intermediate or silicic. Temperature, pressure, and volatile content also play a role in magma classification.
An eruption is classified as an explosive volcanic eruption based on the amount of which mineral found in the magma?
An eruption is classified as explosive primarily based on the amount of silica (SiO2) found in the magma. Higher silica content increases the viscosity of the magma, preventing gas from escaping easily, which leads to the buildup of pressure and ultimately results in explosive eruptions. Conversely, magma with lower silica content tends to be less viscous and allows gases to escape more readily, resulting in less explosive activity.
Is the mt paricutin volcanoes magma mafic intermediate or felsic?
Like most cinder cones Paricutin was fed by mafic magma.
Does magma having a silica content of 50 percent is more mafic than one having a silica content of 70 percent?
No, magma with a silica content of 50 percent is more felsic, while magma with a silica content of 70 percent is more mafic. Silica content is inversely proportional to magma's mafic or felsic classification.
How is magma classified?
Magma is classified based on its silica content, which determines its viscosity and behavior. Magma is typically classified into four main types: basaltic, andesitic, rhyolitic, and dacitic, based on their silica content and mineral composition. These classifications help geologists understand the types of volcanoes and eruptions that can occur.

What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)
What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)

How are related literature and studies classified?
They are classified according to the research's ideas wherein each classification is distinguished by the essence of content and its applicability.
Does magma having a silica content of 50 percent is more mafic than one having a silica content of 70 percent?
No, magma with a silica content of 50 percent is more felsic, while magma with a silica content of 70 percent is more mafic. Silica content is inversely proportional to magma's mafic or felsic classification.
What two properties of magma determine what kind of volcano will form?
The silica content and the gas content of magma are two properties that determine what kind of volcano will form. Magma with low silica content and low gas content tends to form effusive, shield volcanoes, while magma with high silica content and high gas content tends to form explosive, stratovolcanoes.
What is a magma's viscosity directly related to?
A magma's viscosity is directly related to its temperature and silica content. Higher temperature and lower silica content typically result in lower viscosity, making the magma more fluid and runny. Conversely, lower temperature and higher silica content lead to higher viscosity, resulting in a thicker, more sticky magma.
