The volcanic aerosol cloud forms in several weeks by the conversion of sulfur dioxide SO to sulfate aerosol and its subsequent microphysical transfor mations The resulting cloud of sulfate aerosol particles with a residence time of a couple of years developments since 2010. © Crown copyright Met Office.

Volcanic ash can cause engine failure. Where do volcanoes occur—and why?. Divergent [MOR] boundaries . About 75% of erupted lava is found here. Basaltic magma; low viscosity, therefore it flows easily!. Oceanic crust ranges from about 2 km to 10 km thick. Betty Croft. 1. , Jeff Pierce. 1,2. and Randall Martin. 1,3. 1.

Smaller sizes are lofted higher where they freeze→ latent heat release leads to increased buoyancy and a stronger updraft. By Karanasiou Katerina B1. 07/02/2017. Volcano…. Volcano is open passageway from the interior of the Earth that allows blast rock and gases from the interior to the cortex surface in the form of lava. This activity creates mountains.
