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.
There are four different types of volcanoes. A volcano is categorized both by formation and appearance. Different types of volcanoes also indicate the types of expected eruptions. The different types of volcanoes are: composite (or stratovolcanoes), shield, cinder cones and spatter cones.Throughout the world, one can see pictures of the four types of volcanoes, each type indicative of the active underground world we often view as static.ayers of rock and lava form composite volcanoes. Composite volcanoes release lava and rock when they erupt. Identifying a type of volcano helps predict the kind of eruption to expect from it. The lava of a spatter cone volcano has a continuous flow. Lava, ash, and gases are ejected through a volcano vent.
