A Volcano is an opening in the earth’s crust through which lava, ash, and gases are ejected. Most volcanoes have steep sides, but some can also be gently sloping mountains or even flat tablelands, plateaus, or plains. The volcanoes above sea level are the most popular, but the majority of the world's volcanoes lie beneath the sea, formed along the global oceanic ridge systems in the deep ocean floor. According to the Smithsonian Institution, 1511 above-sea volcanoes have been active during the past 10,000 years, 539 of them erupting one or more times. An average of 50 to 60 above-sea volcanoes worldwide are active in any given year; about half of these are continuations of erupt
