Pyrolysis of cellulose produces what?
The Saffir-Simpson scale is used to measure the intensity of what?
When approaching the Western Hemisphere, hurricanes commonly move north on clockwise-curving paths due to what?
larger numbers to describe larger disasters.
Of the disaster scales discussed in the book (Richter, Modified Mercalli, Fujita, Saffir-Simpson) use what to describe the extremity of a natural disaster?
What month historically has more hurricanes than any other month?
The most famous of the ice-dam failure floods is preserved in the "channeled scablands" topography in what state?

storm surges that flooded coastal areas
