DESCRIPTION:Iconic examples of volcanic eruptions include Hawaiian fire fo
 untains and large billowing eruption columns. These phenomena are caused b
 y gases (mostly water) that are dissolved within the molten rock (magma) a
 t depth but form bubbles as the magma rises to the Earth's surface. To und
 erstand the processes involved\, we will start with something more familia
 r that you may even have with you the bubbles in carbonated drinks. From t
 here we will talk about how bubbles drive explosive eruptions\, what we ca
 n learn from the bubbles preserved in volcanic rocks\, and the role of bub
 bles in producing volcanic ash.
