Human Impacts: Atmosphere
Global Warming Definition:An increase in the average temperature of earth because of an increase in greenhouse gases.
Global Warming Cause: A ‘blanket’ of greenhouse gases keeps Earth warm. Hot dog
Global Warming Gasses such as carbon dioxide and methane trap heat and help our planet support life. This is called the greenhouse effect. It is normal, and essential to life. Cause:
Global Warming Cause: Increased production of greenhouse gases has enhanced this warming effect, called global warming.
Global Warming Effect: Changed precipitation patterns.Rise in sea levels and coastal flooding due to melting glaciers.
Global Warming Solution:Reduce carbon dioxide emissions by using less fossil fuel. Explore alternative energy source. Big guy in a little car
Acid Deposition Definition:Rain ( and snow, hail, etc.) with a pH below 5.6 Harmful chemicals settle as “dust”
Acid Deposition Cause:Sulfur dioxide and nitrogen dioxide pollution from the burning of fossil fuels.
Acid Deposition Cause:Most of New York State’s acid precipitation originates in the mid-west and moves to us in the prevailing winds.
Acid Deposition Effect:Destruction of limestone and marble monuments due to increased chemical weathering Acidification of aquatic ecosystems destroying the life in them.
Acid Deposition Effect:Damage forests and other plants in a variety of ways
Reduce use of fossil fuelAcid Deposition Solution: Reduce emissions sulfur and nitrogen from industry by use of scrubbers etc. Explore alternative energy sources. . Reduce use of fossil fuel
Ozone Depletion Definition:The reduction of the thin layer of O3 (ozone) that protects the earth from ultraviolet (UV) radiation.
Ozone Depletion Cause:Chloroflurocarbons (CFC’s) pollution from refrigerants and plastics are destroying our thin ozone shield high up in our atmosphere.
Ozone Depletion Effect:It is linked to increased incidence of skin cancers and cataracts in the human population. Increased UV radiation has been linked to amphibian declines.
Ozone Depletion Solution: Ban CFC’s
Human Impact on Air Resources
Impact of Human Population on the Environment
Acid Precipitation Found under different forms : snow, rain, drizzle, fog… Gas : nitrous oxides (NOx) and sulphur dioxyde (SO 2 ) in the air Nature.

Overpopulation ~7 billion people Many natural resources are nonrenewable More people means: –1) More forests removed –2) More resources consumed –3)
Aim: How is the earth's atmosphere similar to a greenhouse?

ENVIRONMENTAL SCIENCE II FINAL EXAM REVIEW UNIT 3: AIR POLLUTION Final Exam will be on Wednesday June 10, 2015 The final exam is worth 20% of your final.
Ozone & Greenhouse Effect. What is Ozone? Ozone is a molecule that occurs in the Stratosphere Ozone absorbs harmful UV rays from the sun O 3 + uv O 2.
Greenhouse Effect - Natural Heating of Earth’s surface by certain atmospheric gases.
Pollution. Smog smog – mixture of chemicals that forms a haze in the air (Nitrogen Oxides etc) smoke from cars and factories release the chemicals.
