~How do volcanoes form~
Volcanoes form when magma from the earths upper mantle works its way up to the surface, it erupts to form lava flow and ash deposits and over time the volcanoes eruption will begin to get bigger and bigger and eventually calm down.
~My volcano~
The name of the volcano i will be researching is called Mount Ruapehu, this volcano is one of the more active volcanoes in the Taupo Volcanic District in New Zealand. It has been erupting regularly since 1996 but the most recent major eruption was in 1995-1996 and affected 100.000 people in the central north island. The 1996 eruption produced at least seven million tonnes of ash and 2.3 million falling on Lake Taupo, drinking water contamination had a big impact on the people and animals which lived on the countryside as it blocked alot of the water ways and as well as metal structures and vehicles were affected by the ash.
~Stories~
This link is a story on how Mount Ruapehu had Taranaki and Tongariro fight over her and Taranaki ended up loosing and having to move away. This is
In science today we erupted our volcanoes which we have been working on for a few weeks as you can see above is the volcano i was researching but as we had to get into groups my group and I decided to create and erupt the volcano that presayus researched named Mount Etna.
For this experiment we had to use 4 spatulas of potassium iodide in 20ml of water which speeds reaction up and 35% hydrogen peroxide, dish washing liquid and food coloring.
This is the end result of our volcano.
This is a video of our eruptions.
