Volcanoes

• Shield volcano


  A broad, shallow volcanic cone, which arises because the running lava, which is fluid and hot, cools slowly
• Dome volcano


  A steep, convex slope from thick, fast-cooling lava
• Ash-cinder volcano


  Throws out - besides lava - much ash into the air. Through this the volcanic cone is built up from alternate layers of ash and cinder
• Composite volcano


  Built up from alternate layers of lava and ash but, besides its main crater, it has many little craters on its slope
• Caldera volcano


  An older volcano with a large crater which can be 62 miles(100km) wide. In this crater many little new craters are formed
