If this process occurs underneath a glacier, then sideromelane may be produced.
If this process occurs underneath a glacier, then sideromelane may be produced. Density currents generated by this process deposit ignimbrite. The mixing of groundwater with the products of this process leads to the creation of maars. A type of this process involves the formation of gas slugs, tuff, and the creation of cow-pies, so named because they resemble manure. More generally this process produces a namesake column whose height is proportional to the silica content of the (*) liquid involved. Types of this process include phreatic, which leads to an explosion of steam, or Strombolian, in which lapilli, ash, and bombs are expelled as tephra. For 10 points, name these events which might occur in active, but not extinct, volcanoes.
