Why do cinder cones form steep little volcanoes?
Quick Answer
They are built from fragments of lava that fall back around the vent. Loose cinders and scoria pile up at a steep angle of repose.
The Full Story
Cinder cones form when gas-rich magma throws out blobs and fragments that cool in the air and land around the opening. Because the material is loose and chunky, it cannot spread out far before coming to rest. The result is a small, steep-sided cone, often with a crater at the top. Many cinder cones form in volcanic fields rather than at a single giant central volcano. Sunset Crater in Arizona is a well-known example from around the 11th century CE.
