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.
Volcano Shapes. Most land volcanoes have the same basic structure, but volcano shape and size varies considerably. There are several elements that these different volcano types have in common are: 1  a summit crater-the mouth of the volcano, where the lava exists.2  a magma chamber-where the lava wells up underground.onsequently, its composition, shape and structure are all determined by the nature of the volcanic material and the nature of the eruption. The three main volcano shapes are: 1  Stratovolcanoes: These are the most familiar type of volcanoes, and generally have the most destructive history of eruptions.
