And steep Division Like a volcano cone type alternately Volcanic eruptions are often as big as a volcano Mauna Loa (Hawaii) , volcanic cones, pebbles (Cinder Cone) cone is extremely steep. And the lava ejected fragments. The lava is viscous Continuous flow And resembles a lava ball. Ejected from a single vent.
