Global Firestorm The material ejected from the impact through the hole in the atmosphere will re-enter all over the globe and heat up from the friction with the atmosphere. The chunks of material will be hot enough to produce a lot of infrared light. The heat from the glowing material will start fires around the globe. Global fires will put about 7 × 10 10 tons of soot into the air. This would "aggravate environmental stresses associated with the . .. impact." Acid Rain The heat from the shock wave of the entering asteroid and reprocessing of the air close to the impact produces nitric and nitrous acids over the next few months to one year. The chemical reaction chain is: a. N 2 + O 2 ‚> NO (molecular nitrogen combined with molecular oxygen produces nitrogen monoxide) b. 2NO + O 2 ‚> 2NO 2 (two nitrogen monoxide molecules combined with one oxygen molecule produces two nitrogen dioxide molecules) c. NO 2 is converted to nitric and nitrous acids when it is mixed with water. These are really nasty acids. They will wash out of the air when it rains---a worldwide deluge of

Unformatted text preview: acid rain with damaging effects: destruction or damage of foliage; great amounts of weathering of continental rocks; the upper ocean organisms are killed. These organisms are responsible for locking up carbon dioxide in their shells (calcium carbonate) that would eventually become limestone. However, the shells will dissolve in the acid water. That along with the "impact winter" (described below) kills off about 90% of all marine nanoplankton species. A majority of the free oxygen from photosynthesis on the Earth is made by nanoplankton. The ozone layer is destroyed by O 3 reacting with NO . The amount of ultraviolet light hitting the surface increases, killing small organisms and plants (key parts of the food chain). The NO 2 causes respiratory damage in larger animals. Harmful elements like Beryllium, Mercury, Thallium, etc. are let loose....
