Answers
Answer:
and 1. Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.
ans2. Average global sea level has increased eight inches since 1880, but is rising much faster on the U.S. East Coast and Gulf of Mexico. Global warming is now accelerating the rate of sea level rise, increasing flooding risks to low-lying communities and high-risk coastal properties whose development has been encouraged by today's flood insurance system.
ANS 3. Eutrophication is the process by which a body of water becomes enriched in dissolved nutrients (as phosphates), stimulating the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen.
