A volcano is a conical hill or mountain formed by material from the mantle being forced through an opening or vent in the Earth's crust. There are three types of volcanoe. The first is active. These are volcanoes that have erupted in the last recently and is likely to erupt again. Mount Etna in Sicily is an active volcano. The second is dormant. These are volcanoes that havent erupted or shown signs of erupting for 2000 years but could still become active in the future. Mount Baker in Washington is a dormant volcano. The third is extinct. An extinct volcano is one that will never erupt again. The sugarloaf in Ireland is an extinct volcano.
