Why do volcanoes erupt?
An eruption is caused by the plates rubbing together. The magma is forced to rise in the air, then hot lava runs down.
The volcano is caused to rise by the pressure of the plates rubbing so the magma is forced from the magma chamber and blow the top of a mountain. Other parts of magma burns through other parts of the mountain to create a ‘vent’. The crater is blown, causing flying ashes and rocks. The heat emits a very hot cloud of smoke which is toxic from the sulphur which turns the water to acid.
When a volcano erupts, the lava travels and burns everything in its path. It could also be useful because the fragments of the rocks are absorbed by the soil, making it to become fertile for plants.
Volcanoes can be very dangerous (and should be aware of). If you see smoke coming out from a mountain, there’s a chance it could be a volcano!
Learning Intention: We are learning to follow the structure of an explanation.
Success Criteria: I know I can do this when I explain why volcanoes erupt by starting with an introduction, followed by the explanation, then the effects and then a concluding sentence.
