Volcano
From Simple English Wikipedia, the free encyclopedia
A volcano is a mountain where lava (very hot, molten rock) comes from a magma chamber under the ground. Most volcanoes have a crater at the top. Magma is called lava once it has come out the volcano.

[edit] How volcanoes are made
Most volcanoes are made where giant slabs of rock that make up the world, called plates, crash into each other. These plates move over each other, causing magma to rise to the top through weak places in the crust.
