Question

Quizplus · Accepted Answer

Stratovolcanoes, also known as composite volcanoes, are characterized by their steep slopes and alternating layers of tephra (volcanic ash and other ejected material) and solidified lava. Cinder cones are small, steep-sided volcanoes made of loose volcanic debris, while shield volcanoes have gently sloping sides and are composed mainly of lava flows. Fissure volcanoes erupt from long cracks in the Earth's surface rather than a single vent.
