An asymmetric formation of matter from one of these entities can result in a coulee, such as the phonolite-created ones in western Saudi Arabia, Chao, and Mono Lake.

When that matter is rich in alkali elements, it is classified as a natrocarbonatite, which is commonly seen as driblet cones called hornitos. The vesiculation and umbrella regions characterize the (*) events associated with these entities, which can produce "pillow" formations when occurring underwater and often exhibit pahoehoe flows. These entities leave behind calderas, and those that converge in a steep summit are known as the "strato" variety. For 10 points, name these openings in the Earth which spew magma and ash during eruptions.
