The cinders are loose pieces of rock that landed near the erupting volcano, thus building up and making the cone shape. Usually look like craters too. Lava will flow in the initial stages of eruption, but the rest will be ejecta, in the form of volcanic bombs and pieces of solid rock.

These tend to look like the traditional volcanoes, where you have a mountain with a hole at the top, except some tend to not have holes, but dome within the volcano, These are the shape they are due to the lava cooling and building upon itself over time. Some of these with have weakness off to the sides where another opening will occur. When it erupts 2 things can happen, Magma will flow (which usually is fast due to the composition) or pyroclastic flows will result, which is pieces of solid material, gas, and ash that is super hot and flows super fast. Usually can only see ash and gas flowing towards you Pyroclastic flow image: http://www.holoscience.com/news/img/Pyroclastic_flow.jpg<br><b>References : </b><br>Physical Geology Class Image of cinder cone: http://mivo-sys.tripod.com/images/cinder_cone.jpg
