Web38 .Rhyolite is a felsic volcanic rock with high silica content, which can make the magma more viscous and prone to explosive eruptions. 39. Shield volcanoes have gentle slopes and tend to erupt effusively, producing mostly lava flows and volcanic gases, rather than explosive eruptions that generate pyroclastic flows and ash clouds. 40.

Volcanic rocks are named according to both their chemical composition and texture. Basalt is a very common volcanic rock with low silica content. Rhyolite is a volcanic rock with high silica content. Rhyolite has silica content similar to that of granite while basalt is compositionally equal to gabbro. Intermediate volcanic rocks include andesite, dacite, trachyte, and latite.
