Smog smog – mixture of chemicals that forms a haze in the air (Nitrogen Oxides etc) smoke from cars and factories release the chemicals
Temperature Inversion Cold winter air is held down by warm air above it. It stays near the earths surface trapping smog
Chloroflourocarbons CFC’s are chemicals formerly used in A/C’s, spray propellants and Styrofoam.
Ozone Depletion CFC’s destroy the ozone layer once they reach the stratosphere. This let’s too much UV light in.
Greenhouse Gases Gases able to absorb heat energy. Most common is carbon dioxide from fossil fuels.
Greenhouse effect Sunlight warms the earth but the extra heat is held close to the earths surface by greenhouse gases.
Global Warming increase of the average temperature of the earth Hypothesized to continue rising (could lead to problems)
Acid rain Rain mixed with acid from the smoke of fossil fuels (sulfur) - changes ph of soil and lakes
Eutrophication -eutrophication- adding extra nutrients to the ecosystem (N,P) -gets in water and causes extra algae to grow
continued -bacteria decompose dead algae and use up the oxygen that fish need to breath
Oil Spills Oil is spilled into the ocean Major affects on the ecosystem.
Landfills Liquids from landfills can seep into ground water Methane gas from landfills can seep into basements Plastic not biodegradable
Radiation Radiation released from mining and drilling uranium gets into air and water Nuclear waste from power plants must be buried.
Asbestos Long fibers that used to be used as insulation and fire fireproofing in buildings. Harmful when breathed.
Smog Effects Asthma attacks, upper respiratory problems (bronchitis)
Ozone Depletion Effects Too much UV causes skin cancer, cataracts, harms plankton and crops
Global Warming Effects Melts ice caps causing rising sea levels Changes climate (hurricanes, etc) Droughts
Acid Rain Effects Dissolves metals into water that can harm fish, crops and humans. Erodes structures
Eutrophication Effect Decreased oxygen in water causes major disruption in the food web.
Oil Spill Effects Oil poisons aquatic organisms. Impacts fishing economy (BP oil spill 10’)
Landfill Effects Polluted water raises water treatment costs
Radiation Effects Radon radiation is the number 2 cause of lung cancer in the US Radiation sickness and burns
Asbestos Effects Breathing in Asbestos cuts and scars the lungs
STRAND 4 EARTH AND SPACE SCIENCE ESS.8.8.1
Human Impact on Air Resources
Impact of Human Population on the Environment

Earth Science 4.3 Water, Air, Land Resources
Greenhouse gases in the atmosphere absorb and retain the energy radiated from land and ocean surfaces, thereby regulating Earth’s average surface temperature.
Air Pollution TSWBAT: Define air pollution.
Chapter 5 Vocabulary air pollution emissions photochemical smog ozone acid rain ozone layer chlorofluorocarbons (CFCs) greenhouse effect global warming.
Aim: How is the earth's atmosphere similar to a greenhouse?
What do you think this means?. Learning Targets 8. Identify the causes and effects of pollution on Earth’s cycles. 9. Explain how pollution affects.
Sustainable Use of Resources
AIR POLLUTION Composition of Air:
Issues with the air.
How are we affecting the Environment?. 1. Air pollution a.Smoke, dust and exhaust fumes will pollute the air b. Smog – a form of air pollution that is.
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.
Human Impact on the Environment:
The environment is all of our surroundings. This includes the atmosphere, oceans, soil and all living things.
