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.
How does the coposition of the magma affect the temperature at which it solidifies?
The composition of the magma is very important for solidificatoin temperature. When it starts to cool, crystals of minerals begin to grow. If it has a low silica content - which means high melting point - the magma will solidify at high temeratures. If it has a high silica content - which means low melting point - it will solidify at lower temperatures.
What are the temperature ranges of liquid magma?
Researching the temperatures of liquid magma has shown that the average temperature ranges are between 700 and 1300 degrees Celsius. On rare occasions the temperature can be as low as 600 or as high as 1600 degrees celsius.
Magma that is relatively thin dark colored and low in silica?
A low silica magma is called a "mafic" magma.
Which conditions make for a violent volcanic eruption?
Magma with low viscosity

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)
Magma that is low in silica and produces nonexplosive eruptions?
Low viscosity mafic magma.

Is styrofoam dry ice?
No. Dry ice is frozen carbon dioxide, which can only exist at extremely low temperatures. Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam often used for thermal insulation and craft applications.
Are gases more soluble at high or low temperatures?
low temperatures
What causes abnormally low body temperatures?
Continued exposure to low or rapidly falling temperatures.
What is Bowen's reaction series?
Bowen's Reaction scale lists the order in which minerals crystallize. Olivine or ultramafic minerals are the first to crystallize. They do so at high temperatures, whereas quartz is the last to crystallize, and at low temperatures. Through Bowen's many studies, he found that the order of magma from high to low temperature is ultramafic, mafic, intermediate, and felsic. Plagioclase feldspar follows the crystallization of olivine.
