There are three main types of volcanoes: shield volcanoes, composite volcanoes (also known as stratovolcanoes), and cinder cone volcanoes. Shield volcanoes have broad, gently sloping sides and are built up from layers of lava flows. They are typically formed by non-explosive eruptions and are characterized by their large size. Composite volcanoes, on the other hand, are made up of alternating layers of lava, ash, and rock fragments. They have steep sides and are formed by both explosive and non-explosive eruptions. Lastly, cinder cone volcanoes are small, cone-shaped volcanoes that are formed by explosive eruptions that eject volcanic ash, cinders, and rock fragments. They typically have a symmetrical shape and can be found on the flanks of larger volcanoes.
