Strata vs Shield Volcanoes

 A stratovolcanois also known as a composite volcano, it is a tall conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes stratovolcanoes are characterized by a steep profile and periodic, explosive eruptions is was causes them to build up. The lava that flows from typically cools and hardens before spreading far. The magma forming this lava is often felsic, having high-to-intermediate levels of silica with lesser amounts of less viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as alomst 9 and a half mils still that big a small town could bw distored.
