Why does magma viscosity vary with silica content?
A) Increasing silica content lowers the melting temperature and since increasing the temperature of a magma decreases viscosity increasing silica content increases viscosity.
B) There is no correlation between silica content and magma viscosity.
C) Increasing silica content increases the amount of water a magma can dissolve and water decreases magma viscosity, so increasing silica content decreases magma viscosity.
D) Increasing silica increases a tendency for silica bonds to link up in networks, acting like a polymerization of the magma.
