Below is an extract from Erin's explanation text about volcanoes. We have focussed on using technical vocabulary in order to inform our readers of the features of a volcano.
Volcanoes are mountains which contain vents through which magma is pushed up from underneath the earth's crust.
What is a volcano?
A volcano is normally seen as conical mountain or hill.It is a rupture on the crust of a planet. A vent inside the volcano allows lava, hot vapour and gases to exit the magma chamber. The word 'volcano' finds its origins in the name 'Vulcan'.Vulcan was the Roman god of fire, when volcanoes errupted the Romans believed it was due to the anger of Vulcan.
Why do volcanoes occur?
Volcanoes occur because there are 17 tectonic plates that make up the earth's crust, they float on the hotter layer of mantle. Where the plates come together or pull apart, volcanoes are formed. The famous Pacific Ring of Fire was made by tectonic plates converging.
A famous eruption
One notable eruption was that of Mt Vesuvius in 79 AD. It was an ordinary summer's day when all of a sudden, birds ceased to sing, the sun clouded over, and without warning, ash and lava tumbled down from the mouth of the volcano.
Erin, I am impressed with your use of technical vocabulary and interesting facts. To improve your writing further, try and include a greater range of punctuation, such as brackets and semi-colons.
