Conclusion paragraph for a cinder cone volcanoe report
Answers
Volcanoes are best defined as cracks in the Earth’s surface where magma has flowed and turned into lava. Volcanoes can be either active, dormant or extinct. While active volcanoes erupt regularly, dormant volcanoes erupted in the past, but do not now; and extinct volcanoes have never erupted and scientists do not expect that they will.
Scientists also classify volcanoes further as to their form. These forms include fissure volcanoes, composites, cinder cones, shield volcanoes and lava domes. Fissure volcanoes form when tectonics plates spread apart, while composites form when two plates meet, and one is beneath the other. Composite volcanoes have a crater and several layers of lava and hardened ash and debris. They can erupt because of gas build-ups.
Cinder cones often form on other volcanoes as cooled lava and usually only erupt once. Lava domes can be quite explosive, while shield volcanoes are not. In lava domes, lava can plug the vent causing a build-up, which can lead to an eruption. Shield volcanoes are mainly comprised of many different layers of hardened lava
