Silica is like sugar added to water. The more sugar, the more viscous it becomes. In magma, the more silica it has, the more viscous it is. Magma with higher silica content tends to have a higher viscosity, making it thicker and leading to more explosive volcanic eruptions due to the increased trapping of gases. • The silica content in basaltic magma is approximately 50%, in andesitic magma it's around 60%, and in rhyolitic magma, it reaches about 70%. Among these, basaltic magma, with the lowest silica content, is the least explosive; andesitic magma, with an intermediate silica level, is moderately explosive; while rhyolitic magma, having the highest silica content, is the most explosive. • Contact: [email protected]
