Detailed explanation-1: -Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
Detailed explanation-2: -Cinder cones are simple volcanoes which have a bowl-shaped crater at the summit and steep sides. They only grow to about a thousand feet, the size of a hill. They usually are created of eruptions from a single opening, unlike a strato-volcano or shield volcano which can erupt from many different openings.
Detailed explanation-3: -Cinder cones are the type of volcano that is formed by pyroclastic fragments like volcanic ashes, solidified lava pieces, volcanic clinkers, pumice and hot gases. These volcanoes are formed around the volcanic vent and are known to be the simplest form of a volcano.
Detailed explanation-4: -Cinder cones are the most common type of volcano in the world. They may look like an idealized depiction of a volcano as they are steep, conical hills that usually have a prominent crater at the top.
Detailed explanation-5: -Mechanics of eruption They are composed of loose pyroclastic material (cinder or scoria), which distinguishes them from spatter cones, which are composed of agglomerated volcanic bombs. The pyroclastic material making up a cinder cone is usually basaltic to andesitic in composition.
