Model 1

A Volcano is a piece of the Earth that allows hot lava, volcanic ash and gases to escape from a magma chamber below the Earth. The Earths Volcanoes take place because the Earths crust is split into 17 undecidable tectonic plates that float on a hotter, softer layer in it's mantle. Scientists have put the categories of the volcanoes into three main stages, active, dormant and extinct. An active volcano is when a volcano has just erupted and will soon erupt again. A dormant volcano is when a volcano hasn't erupted in a long time, but still has the possibility of erupting again, so it's technically sleeping. A extinct volcano is when the volcano erupted thousands of years ago and there's no possibility of it erupting again.Most new Zealand volcanoes are dormant.
