What else can I help you with?
What is meant by the term viscosity when used in describing magma?
The ease with which it flows or how thin or thick it is. the more solid it is the higher the viscosity. As in Oil the thicker it is the higher the viscosity machine oil low viscosity, gearbox oil high viscosity.
Which conditions make for a violent volcanic eruption?
Magma with low viscosity
What type of magna has a low silica content?
Magma with low silica content is typically referred to as mafic magma. Mafic magma is characterized by its high temperature and low viscosity, which allows for the eruption of lava flows. This type of magma is commonly associated with basaltic rocks.
Where does the viscosity of magma depends?
1. Chemical Composition of the magma. 2. Concentration of the melt. 3. Presence of Volatiles. 4. Amount of Water present in the magma.
Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
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)
What is meant by the term viscosity when used in describing magma?

WHAT ARE THE THREE TYPES OF MAGMA AND THE DIFFERENCES?
The three types of magma are basaltic, andesitic, and rhyolitic. They differ in their silica content, viscosity, and eruptive behavior. Basaltic magma has low silica content, low viscosity, and tends to erupt quietly, while rhyolitic magma has high silica content, high viscosity, and tends to erupt explosively. Andesitic magma falls in between these two in terms of composition and behavior.
What 3 factors determine magma viscosity?
The three elements that determine viscosity in magma are:TemperatureSilicaOxides (gases)Viscosity changes the way in which magma will flow. Magma with low viscosity will flow much more easily than high viscosity magma.

What are the 3 types of magma?
basaltic magma ,Andesitic magma and Rhyolitic magma
What is magma that has a low silica content called?
Magma with low silica content is called mafic magma. It is characterized by its high temperature, low viscosity, and dark-colored minerals like olivine and pyroxene. Mafic magma typically erupts from shield volcanoes and is associated with basaltic rocks.
Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
Where does the viscosity of magma depends?
1. Chemical Composition of the magma. 2. Concentration of the melt. 3. Presence of Volatiles. 4. Amount of Water present in the magma.
What two factors control the explosiveness of an eruption?
The explosiveness of an eruption is primarily controlled by the viscosity of the magma and the amount of gas trapped in it. Low viscosity magma with high gas content tends to lead to more explosive eruptions, while high viscosity magma with lower gas content leads to less explosive eruptions.
