Volcano - Formations
What is a volcano?
A volcano is a mountain formed from solidified lava from different eruptions. Lava that flows out can come from 30 to 60 kilometres,from inside the Earth.

Where are volcanoes found?
Volcanoes are usally found near the boundaries of continental plates,which form the Earth’s outer layer.

How a volcano is formed?
A volcano is formed by pressure building up below the Earth’s crust. Magma forces it way through weaknesses in the earth's crust. When the magma emerges it is called lava. When it cools, it solidifies into rock,or it may emerge though thin cracks,which are called fissure.Or it may be forced though wider pipes,that starts to build up, to a volcano.

The shapes of volcanoes?
The shapes of a volcano, depends on what type of lava.Viscous lava,is thick and sticky,that cools quickly,which can solidify building up steep sided cones.Non viscous lava,is this and runny,that can flow for several kilometresbefore it cools.
These are some of volcanoes.
• Sheild volcanoes,are shaped like upturned saucers,withgental slopes.
• Cinder cone volcanoes arehigh,with steep slopes.
• Stato volcanoes are cone-shaped mountains.
