Volcanic Model

I am learning to create a volcanic model.

Today we reflected about our volcanic model that we made in our science class. The model that I did was one that was talking about the ash plume which is caused by the interaction of lava and ice. It also talks about one of the boundaries which is called the Divergent boundary and also the Magma inside the volcano.

What we had to do for this activity was cut out the pieces then glue it together to form the model. There was another one which was talking about volcano itself.

How do volcanic eruptions happen? Volcanic eruptions happen from either other natural disasters or when the tectonic plates in the volcano separate. Is volcanic eruptions very common in New Zealand? if so why? Volcanic eruptions are not common in New Zealand because the last eruption was about 500-1000 years ago.
