The three different types of lava differ in composition and flow rate. Rhyolitic lava is the slowest moving type of lava, since it has a high viscosity due to a high silica concentration. Basaltic lava is the fastest moving lava because of its low viscosity resulting from a low silica content.
There are four different types of volcanoes. A volcano is categorized both by formation and appearance. Different types of volcanoes also indicate the types of expected eruptions. The different types of volcanoes are: composite (or stratovolcanoes), shield, cinder cones and spatter cones.Throughout the world, one can see pictures of the four types of volcanoes, each type indicative of the active underground world we often view as static.ayers of rock and lava form composite volcanoes. Composite volcanoes release lava and rock when they erupt. Identifying a type of volcano helps predict the kind of eruption to expect from it. The lava of a spatter cone volcano has a continuous flow. Lava, ash, and gases are ejected through a volcano vent.
