Volcanoes/Volcanology/Quiz

Volcanology is a lecture from the school of geology and the department of radiation astronomy about the science that studies volcanoes.

Volcanic ash consists of rock, mineral, and volcanic glass fragments smaller than 2 mm (0.1 inch) in diameter, which is slightly larger than the size of a pinhead. Credit: D.E. Wieprecht, USGS.
