Detailed explanation-1: -Composite volcanoes are steep-sided volcanoes composed of many layers of volcanic rocks, usually made from high-viscosity lava, ash and rock debris. These types of volcanoes are tall conical mountains composed of lava flows and other ejecta in alternate layers, the strata that give rise to the name.
Detailed explanation-2: -Composite cones are tall, cone shaped volcanoes that produce explosive eruptions. Shield volcanoes form very large, gently sloped volcanoes with a wide base. Cinder cones are the smallest volcanic landform. They are formed from accumulation of many small fragments of ejected material.
Detailed explanation-3: -Composite volcanoes are probably the most complex type of volcanic edifice as they experience multiple eruptions, erupt lavas with a range of compositions, and experience many different types of eruptions. They may have multiple vents, but most composite cones have a main vent at the summit.
Detailed explanation-4: -They are made of small fragments of rock, called cinders. These cinders can be mafic, intermediate, or felsic in composition. Most composite and shield volcanoes have nearby cinder cones.
Detailed explanation-5: -Additionally, cinder cone volcanoes have slopes predominantly made of small fragments of ash, cinder, and small volcanic materials. Composite volcanoes, on the other hand, have slopes made of alternating layers of larger pyroclastic fragments and layers of cooled felsic lava.
