Seminar 5 - Volcanoes

Linking nicely to Seminar 4, No. 5 is on the subject of Volcanoes, which are the source of many of the finer grained igneous rocks.  I cover the type of volcanoes, eruption styles and eruption products.  Some famous eruptions are considered as well with observations on some of the volcanoes which can be seen around the world.  The topic of whether volcanic eruptions can be predicted is also discussed.

The next Seminar in sequence, No. 6 will look at the third and last of the rock groups, the Metamorphic Rocks.
