PDF-Volcanic Eruptions Alan Robock Vo l u m e The Earth

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.

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.

Environmental Sciences. , Rutgers University. More than 2,000 years ago, Pompeii was a busy Roman city near the sleeping volcano Mount Vesuvius. People did not see Vesuvius as much of a threat. Everything changed when Vesuvius suddenly erupted and buried the city in a deadly blanket of ash that was almost 20 ft. thick!. Matthew Toohey. 1. Kirstin . Krüger. 1,2. , . Claudia .
