Cinder cones are a type of volcano characterized by their steep, conical shape. They are formed from volcanic ash, cinders, and small rocks that accumulate around a single vent during explosive eruptions. These eruptions typically produce lava fountains that cool and fall back to the ground, creating the cone structure. Cinder cones are usually smaller than other types of volcanoes, such as shield volcanoes or stratovolcanoes. They can be found in various locations around the world, often in volcanic fields. Some well-known examples include Paricutin in Mexico and Sunset Crater in Arizona.
