Mafic lava is viscous compared to felsic lava. 2. Mafic lava dominates mid-ocean ridges, while felsic lava is found mostly at convergent areas. 3. Mafic lava flows more easily than felsic lava, and the former has a lower risk of exploding. Since felsics tend to cap steam and other gases, explosive eruptions are more likely.
