Two Types of Impact Craters. Impact craters can be categorized in one of two ways: simple or complex. A simple crater has a smooth bowl shape small with a small depth to diameter ratio. This ratio is typically 1:6 which means that if the crater is 1 m deep, it is 6 m wide.
Often cinder cones are classed as a major type of volcano. But cinder cones are much smaller than most shield, composite, and ash flow volcanoes. In fact, cinder cones occur on all of these larger volcano types.Image at left: A schematic representation of the internal structure of a typical cinder cone.here are two stratovolcanoes, one shield volcano, and one volcano that appears to be formed from overlapping stratovolcanoes.
