Question

what range is silica found in magma

Answer 1

Felsic or silicic magmas have a silica content greater than 63%. They include rhyolite and dacite magmas. With such a high silica content, these magmas are extremely viscous, ranging from 108 cP for hot rhyolite magma at 1,200 °C (2,190 °F) to 1011 cP for cool rhyolite magma at 800 °C (1,470 °F).
