precipitation that has a ph of less than that of natural rainwater
it is formed when sulphur dioxides and nitrogen oxides as gases or fine particles in the atmosphere combine with water vapor and precipitate as sulphuric acid or nitric acid in rain snow or fog.
natural sources
emissions from volcanoes and from biological processes that occur on the land in wetlands and in the oceans contribute acid producing gases to the atmosphere effects of acidic deposits have been detected in glacial ice thousands of years old in remote parts of the globe.
the principal cause of acid rain is from human resources
industrial factories power generating plants and vehicles sulphur dioxide and oxides of nitrogen are released during the fuel burning process
when water vapor condenses or as the rain falls they dissolve in the water to form sulphuric acid and nitric acid
while the air is cleaned of the pollutants in this way it also causes precipitation in this way it also causes precipitation to become acidic forming acid rain
canada acid rain is aproblem in canada water and soil sytems lack natural akalinity such as lime base canada consists of susceptible hard rock such as granite
industrial acid rain is a substantial problem in china eastern europe and russia and areas down wind from them acid rain from power plants in the midwest us has also harmed the forests of upstate ny and new england
this shows the effects of acid rain can spread over a large area far from the source of the pollution
harmful to aquatic life increased acidity in water bodies harmful to vegitation increased acidity in soil
accelerates weathering in metal and stone structures
affects human health repiratory probs leeching of toxins can be absorbed by plants and animals brain damage kidney probs and alzheimers disease reduce amount of sulphur dioxide and oxides of nitrogen released into the atmosphere
use cleaner fuels flue gas desulphurisation removes sulphur dioxide from flue gas
liming powered limestone limewater added to water and soil to neutralize acid

2. of the vehicles tested which type performed the best as far as CO2 emissions are concerned? which was the worst? fortwo cause it uses none.
4. were there any trends among vehicles that had high CO2 output? the gas was expensive
5. what surprised you about your dream vehicles? the gas cost to much
6. in your opinion what is the most important output from cars,why? the gas emission because it polluts the air
7. in your opinion what is an acceptable level of CO2 emissions from a vehicle?
8. if you had the money what would be your next car purchase?why?
i would go with a low level 1-3
9. does your decision on which vehicle to purchase fit with your answers to question number7?
green house effect is a natural process necessary for sustaining life on earth is produced by the suns energy and earths atmosphere. energy from solar radiation is emitted toward earth 26% reflected 19% absorbed 55% reaches earth 4% reflected to space 51% absorbed by earths surface. co2 has had 33% increase in concentration in last 200 years comes from burning fossil fuels anything you combust or burn. methan has risen released by huge heards or cattle, greenhouse potential 23. nitrous oxide by product of feedlots greenhouse potential 296. ozone seeves a dual purpose it keeps earth cooler by absorbing radiation before it reaches earth has decreased. CFC's. halo carbon deplete the ozone layer.
GLOBAL CLIMATE CHANGES CAUSED BY HUMANS:
changes in species compositions chemical analyses of ice ice core samples. increase in co2 in the atmosphere causes a greater capacity for warming through the greenhouse effect. melting glaciers,cold spells, heat waves. plants and animals change the way they do things. kyoto protocol 1997 reps talked about how to control global emissions, trying to reduce co2 emissions. carbon sequestration capturing co2 before it goes in the atmosphere
