If the volcano does not erupt anymore it is called a extinct.When a volcano erupts lava comes out but when a volcano is not ready it is called magma.When magma is inside a volcano it is very hot but when it comes out it starts to cool down.In a volcano it has a chamber and a vent.This is what makes the magma come out and turn into lava
volcanoes
Volcanoes are opening in the earth surface .When they are active they can let ash,gas and hot magma escape in sometimes violent and spectacular eruptions.Volcanic eruptions can send ash high in to the air over 30 km above earth surface.Common volcanic gasses include water vapor carbon dioxide,sulfur dioxide,hydrogen chloride,hydrogen fluoride.hydrogen sulfide.
volcanoes
volcanoes could also be found on ocean floor and even under icecaps,such as those found in ice lands.a volcano is a mountain that opens downwards to a pool of molten rock below the surface of the rock.When pressure builds up eruptions occurs.In an eruption gases and rock shoot up through the opening and spill over or fill the air with lava fragments.Eruptionscould cause lava flows,hot ash flows,mud slides,avalanches,falling ash and floods...
