                                   Volcanoes

A volcano is a mountain with vents though which molten lava, ash, cinders and gas erupt, sometimes violently. 

Volcanoes occur along the bounders of the earth's plates, where molten rocks are forced up wards from the magma reservoirs. Some volcanoes are dormant a few are active, which means they may still erupt.

When volcanoes erupt the ashes and rocks shoots out from the inside and lava begins to flow around the mountain burning the grass. Then the lava travels through the land and starts to burn houses cars and more. 

Volcanoes are very dangerous. The lava burns everything in its path so don't go near it. If it erupts, run as far as you can. 

Learning intention: We are learning the structure of an explanation.
Success criteria: I know I can do this when I write an introduction, followed by the explanation sequence, effect and then a concluding sentence about why volcanoes erupt.
