Rhyolitic lava erupts at lower temperatures (800-1000 oC) and contains more silica (> 65 wt. % SiO2) than basaltic lava. Rhyolitic lava is therefore more sluggish, moves more slowly and builds thicker lava flows than basalt. 4. Andesitic lava has a silica content intermediate between basalt and rhyolite (55 - 65 wt. % SiO2) and therefore has flow characteristics intermediate between these two lava types.
