Basalt.Vesicular texture describes an aphanitic rock characterized by preservation of cavities (vesicles) originally filled by escaping gases. Highly vesicular basalts (low-silica magma) are called scoria, whereas highly vesicular rhyolite (high-silica magma) is known as pumice

What does low silica magma form?
Nealy all magma on Earth is originally low-silica, mafic magma. Most magma originates from the upper mantle, which is ultramafic, meaning it has a very low silica content. This rock may partially melt under certain conditions, forming mafic magma, which has a somewhat higher silica content than the mantle rock.
Which flows easier high silica magna or low silica magna?
High silica magma is more viscous (sticky) than low silica magma, so low silica magma lows easier.
Where do mafic and felsic magma originate?
Felsic is a term that means that a rock contains types of silica. Fesic magma is magma that is high in silica particles and low in iron particles.
Magma that is relatively thin dark colored and low in silica?
A low silica magma is called a "mafic" magma.
Do gases escape from a low silica magma easier than it does a high silica magma?
yes
Which is characteristic of the magma that formed the Hawaiian islands?
magma that is low in silica and flows easily

What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)
What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)
Which flows easier high silica magna or low silica magna?
High silica magma is more viscous (sticky) than low silica magma, so low silica magma lows easier.
What are the main magma rocks?
Felsic, high in silica. Mafic, low in silica. Intrusive, those formed underground. Extrusive, those formed above ground.
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 relationship between magma and minerals?
No, magma is molten rock, and it is a semi liquid that exists below the surface (when it's above the surface, it's called lava). When magma cools underground it becomes an intrusive igneous rock which is composed of combinations of various minerals.
Do gases escape from a low silica magma easier than it does a high silica magma?
yes
Does basaltic magma have a lot of silica or very little?
Basaltic magma is low in silica compared to andesitic or granitic magma.
