  1. MUNICIPAL SOLID WASTE
    Waste materials produced in biomes, business, schools and other places in a community
  2. WHAT ARE THE 3 METHODS OF HANDLING SOLID WASTE?
    • 1. Burning
    • 2. Burying
    • 3. Recycling
  3. INCINERATION
    Burning of solid waste
  4. LEACHATE
    A polluted liquide caused by rainwater falling on a dump that has dissolved chemicals from wastes
  5. SANITARY LANDFILL
    Holds municipal solid waste, construction debris, and some types of agriculture and industrial waste
  6. RECYCLING
    Process of reclaiming raw materials and reusing them to create new products
  7. BIODEGRADABLE
    Any material that can be broken down and recycled by bacteria and other decomposers
  8. WHAT ARE THE 4 MAJOR CATEGORIES OF RECYCLED PRODUCTS?
    • 1. Metal
    • 2. Plastic
    • 3. Glass
    • 4. Paper
  9. WHAT ARE THE 3 WAYS INDIVIDUALS CAN HELP CONTROL THE SOLID WASTE PROBLEM?
    • 1. Reduce
    • 2. Reuse
    • 3. Recycle
    • (The 3 "R's")
  10. PESTICIDES
    Chemicals that kill crop-destroying organisms
  11. SEDIMENTS
    Particles of rock and sand
  12. WHAT ARE THE NAMES OF 3 RIVERS IN CONNECTICUT THAT ALL FLOW INTO THE LONG ISLAND SOUND?
    • 1. Connecticut River
    • 2. Housatonic River
    • 3. Thames River
  13. FERTILIZERS
    Are chemicals that provide nutrients to help grow better/they can also cause water to become polluted as it speeds up the growth of algae
  14. WATERSHED
    An area in which, sediments and dissolved materials drain into a common outlet, such as a river, bay, lake, sound or ocean
  15. WATER POLLUTION
    Ant change to water that has harmful effects on people or living things.
  16. OIL SPILL
    • Oil is a pollutant that nature can only handle in small amounts/a spill is too large to handle
    • Oil spills are the most dramatic form of water pollution
  17. HOW DO BODIES OF WATER GET POLLUTED NATURALLY BY THE FALL OF RAIN?
    Water from the water cycle picks up pollutants from the ground and carries them to other bodies of water/when this precipitation accumulation occurs in other bodies of water it can cause natural harm
  18. WHY DO PEOPLE HAVE SUCH A PROBLEM WITH SHORTAGE OF WATER?
    • 1. Most of the water is salty
    • 2. Lots of water is in the form of ice
    • 3. Water is far from area in need
    • 4. Pollutants get into safe water
  19. WHAT IS POLLUTION?
    Emissions of particles and gases, such as carbon monoxide, released into air from factories
  20. DROUGHT
    A period when less rain than normal falls in area
  21. COMPOSTING
    The process of helping biodegradable wastes to decompose naturally
  22. HAZARDOUS WASTES
    A material that can be harmful to human health or the environment if it is not properly disposed of
  23. WHAT ARE THE 4 MAIN CATEGORIES OF HAZARDOUS WASTE?
    • 1. Toxic or poison
    • 2. Explosive
    • 3. Flammable
    • 4. Corrosive
  24. WHAT ARE SOME SAFE WAYS TO DISPOSE OF HAZARDOUS WATSE?
    • 1. Burial in landfills
    • 2. Incineration
    • 3. Breaking down by living organisms
    • 4. Stroring of liquid wastes in deep rock layers
  25. RESINS
    When oil is refined to make gasoline and other petroleum products, these solid materials are left over
  26. FLAMMABLE
    Wastes that catch fire easily that can begin burning at fairly low temperatures
  27. CORROSIVE
    Wastes that dissolve or eat through many materials
  28. RADIOACTIVE
    Wastes that contain unstable atoms/ the atoms give off radiation  that can cause cancer and/or diseases
  29. SHORT TERM AND LONG TERM EFFECTS OF HAZARDOUS WASTES?
    • Short term:
    • 1. irritation
    • 2. Breathing difficulties
    • 3. Internal bleeding
    • 4. Paralysis
    • 5. Coma
    • 6. Death
    • Long Term:
    • 1. Diseases
    • 2. Damage Body
