The composition of magma its temperature & the amount of gasses dissolved in it, together affect the magmas? A. Temperature B.Viscosity C.Pressure D.Seismicity
Felsic magmas are higher in silica and contain lighter colored minerals such as The higher the amount of silica in the magma, the higher is its viscosity. Dissolved gases become trapped by thick magma and the magma chamber. The temperature inside a pyroclastic flow may be as high as 1,000oC (1,800 degrees F.
