1. Volcanoes release mostly: nitrogen, oxygen, and methane, ammonia, and chlorine mercury, carbon monoxide, and gold water vapor, carbon dioxide, and sulfur dioxide
2. Which statement is true: All of our atmospheric "problems" would go away if volcanoes would just stop erupting. Volcanic gases have no effect on ozone. Some large eruptions cool the Earth for short periods. The composition of the atmosphere has been constant throughout earth history.
3. Global warming is primarily cause by: burning fossil fuels volcanoes the El Nino phenomenon long filibusters in Congress
4. Volcanic gases can be measured: by hand using samples collected in a Giggenbach bottle by using a COSPEC on the ground or in a plane by satellite using TOMS by instruments carried through aerosol layers all of the above.
5. Hazards associated with volcanic gas include: asphyxiation crop failure death of livestock due to eating fluorine contaminated gas all of the above.
6. After the 1991 eruption of Mt. Pinatubo, the amount of ozone near the volcanic plume: increased decreased remained the same.
7. The amount of sulfur dioxide released by volcanoes is: greater than man-made sources about the same as man-made sources less than man-made sources
8. The greatest damage to the ozone layer is done by: volcanoes man-made sources, mostly chlorofluorocarbons sea salt none of the above
9. Large historic eruptions have caused average global cooling of: less than 1 degree C between 0.5 and 1 degree C about 5 degrees C about 10 degrees C
10. The greatest amount of global cooling was probably caused by the eruption of: Mount. St. Helens Tambora Paricutin Deccan Traps El Jeremy
