What properties cause some magmas to be more felsic than others?Different minerals crystallize at different temperatures, changing the chemistry.Some parts of the mantle are felsic and some are mafic, creating felsic magma in the crust.Water from subducting ocean plate mixes with the magma to create felsic magmaAnimals change the chemistry of the magma, making it more felsic.Silica content in igneous rocks controls (select the correct term)["texture", "viscosity", "crystal size"] which, in turn, controls ["eruption style", "crystal size"] ...
