Magma and Silica
![]() Pure silica
Silica (SiO2) is a material made of silicon and oxygen, and is one of the 'ingredients" that make up magma. The more silica there is in the magma, the thicker and sticker it is (high viscosity). Magma that has less silica in it is thin and runny (low viscosity). |
