Web36. This is because high silica content magma is more viscous and can trap gases, creating pressure that can lead to explosive eruptions. 37. Mafic magma is less viscous and can flow more easily, allowing it to form thin and long lava flows that can travel far from the vent. 38 .Rhyolite is a felsic volcanic rock with high silica content, which ...
