· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
Because it becomes in contact with oxygen which combines with the original composition. There fore changing the composition and temperature.
High temperature=low viscosityLow temperature=high viscosity

The composition of the magma effects the temperature it will cool and solidify at. In general most magma solidify at about 1,200 degrees Fahrenheit.

1. a decrease in pressure, which lowers the melting temperatures of materials; this occur at mid-ocean ridges. 2. an increase in pressure, which causes materials in the asthenosphere to melt; this often occurs at a hot spot. 3. an increase in the amount of water in the asthenosphere, which lowers the melting temperatures of materials; this often occurs at subduction boundaries.
Mineral composition of the magma, Rate of cooling of the magma, Temperature of the magma, Presence of volatiles and Amount of water present in the magma.
Because it becomes in contact with oxygen which combines with the original composition. There fore changing the composition and temperature.
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.
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
