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.
Let's review. Volcanoes are vents in the earth's crust through which lava, rock fragments, hot vapor and gases are ejected. There are different types of volcanoes based on their size, shape, composition and eruptive style.Composite cone volcanoes are cone-shaped volcanoes composed of layers of lava, ash and rock debris.inder cone volcanoes are steep, cone-shaped volcanoes built from lava fragments called 'cinders.' These volcanic cinders, also known as ' scoria ,' are glassy volcanic fragments that explode from the volcano and cool quickly, building up the sides of the cinder cone volcano fairly quickly.
