Cinder Cone and Composite Cone
उत्तर १

| It is made of small pieces and fragments of solidified lava and ash. | It is made of layers of cinders and ash, alternating with layers of lava. |
उत्तर २
Cinder Cone: Volcanic cones are called Cinder cones when the material erupted consists of cinder and other solid particles. These cones have steep slopes because they consist of particles of large size.
Composite Cone: The volcanoes which start as cinder cone and grown into large volcanic hills with alternating layers of lava and ash are called Composite cones. These cones are formed due to an explosive eruption followed by eruption of lava. Explosive eruption leads to the formation of a layer of ash while lava solidifies as a sheet on the layer of ash. This is followed by a quiet period and then the process gets repeated.
