Detailed explanation-1: -Cinder conesCinder cones, sometimes called scoria cones or pyroclastic cones, are the most common types of volcanic cones. They form after violent eruptions blow lava fragments into the air, which then solidify and fall as cinders around the volcanic vent.
Detailed explanation-2: -Eruption Types & Classification The eruptions of most cinder cones are usually mildly to moderately explosive (Strombolian to Vulcanian), but rarely can have Sub-Plinian activity. Their usually low explosivity is due to the low viscosity and low volatile content of magma.
Detailed explanation-3: -Cinder cones are typically are made of piles of lava, not ash. During the eruption, blobs ("cinders") of lava are blown into the air and break into small fragments that fall around the opening of the volcano.
Detailed explanation-4: -Cinder cones are small volcanoes that consist of volcanic ash, cinders, and other types of tephra that has piled up around a vent.
