What phenomena does Bowen's reaction series help explain? What will be an ideal response?

Question 2

What is viscosity? What is the effect of temperature and composition on the viscosity of magma? At
  the same temperature, which composition of magma will be the most viscous: felsic, intermediate, or
  mafic? Which will be the least viscous? What will be an ideal response?

Answer to Question 1

Bowen's reaction series explains how felsic magmas and rocks can come from mafic magmas, the
order of mineral formation in a cooling magma, how the mineral composition of magma changes with
magma temperature, how magmas become enriched in Si, Al, and K, and the mineral associations that
are common in igneous rocks

Answer to Question 2

Viscosity is resistance to flow. Higher temperature fluids have less viscosity than lower temperature
fluids. In magma, higher silica magmas are more viscous than magmas with less silica. So mafic
magmas are the least viscous, and felsic magmas are the most viscous.
