Answer:
Radial drainage is typical of volcanic cones, so long as they remain more or less intact. Erosion to the skeletal state often leaves the plug standing in high relief, ringed by concentric valleys developed in thick layers of ash.
Verified answer
They form when different types of eruptions deposit different materials around the sides of a volcano. Alternating eruptions of volcanic ash and lava cause layers to form. Over time these layers build up. The result is a cone that has a gentler slope than a cinder cone but is steeper than a shield volcano.
