Describe the composition of a cinder cone


Cinder cones, which are the smallest type of volcano, usually consist of predominantly gravel-sized pyroclastics. Gas-charged eruptions throw molten lava and solid pyroclastic fragments into the air. Falling under the influence of gravity, these particles accumulate around the almost pipe-like conduit for the eruption as a large pile of tephra.
