Acidic lava is different from basaltic lava because it has a higher silica content in it than basaltic lava. The higher the silica level in a lava, the more viscous and less runny the lava is. Also,...
Basaltic lava flows form from mafic magmas located blow the earth's surface. These lava flows, when crystallized, will produce rhyolite and dacite. Intermediate compositions-- that is, a mixture of...
Most composite volcanoes are comprised of Andesitic lava. Andesetic lava has an intermediate silica content compared to granitic with a high silica content and basaltic with a low silica content.
