What rock is formed from low silica magma?
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 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.
How is it possible for magma to have a higher silica content than the rock from which it was formed?
Magma could have higher silica content than its parent rock, if during melting or movement it is gets in contact with silicic country rocks and absorbs them. This is reffered to as Assimillation.
What sedimentary rock turns into the igneous rock basalt?
None. Basalt is formed by the rapid cooling of mafic (silica-poor) magma. It is not formed from sedimentary rock.

What type of magma does cotopaxi have?
blue the cotopaxi volcano has red magma when turned to rock. it also has a high silica content
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 high in silica and produces explosive eruptions?
Magma that is high in silica tends to be more viscous and traps gas bubbles, leading to explosive eruptions. The high silica content increases the magma's explosivity and can result in ash clouds and pyroclastic flows during eruptions. These types of eruptions are characteristic of stratovolcanoes, such as Mount St. Helens.
What is igneous rock formed from magma?
An igneous rock formed from magma is intrusive.
What is the rock formed from the cooling and solidification of magma beneath the surface of the earth?
Its a igneous rock whenit is made formed by magma.
How the earth and its magma are formed?
Magma is formed as a result of very high and intense pressure beneath the surface of the earth that leads to the melting of the rock.
What is granitic magma?
Granitic magma is a type of magma that has a high silica content, which makes it very viscous and prone to forming large plutonic rock bodies, such as granite. It is typically generated in volcanic arcs above subduction zones and is associated with explosive volcanic eruptions due to its high viscosity.
