  • Volcanoes

    A volcano is an opening in the surface of the Earth where hot rock, ash and gases can erupt. Volcanoes that erupt rocks usually form mountains or similar geographical structures. Submarine volcanoes can eventually result in the formation of islands. Most volcanoes are located near tectonic plates.
