Air and Water - Coggle Diagram

- - - - Effects: Causes extinction of some species, increases skin cancer rate
      - How: The greenhouse gases absorbs some UV radiation from the sun, too much of it causes the atmosphere to heat up
      - Increases global temperature
      - Making the Earth in an oven
  - - - Eccentric digestion, it converts sugar into simple molecules for absorption into bloodstream, and methane is a by-product
    - - When bacteria decompose organic plant and animal matter
- - - - Treatment in terms of filtration and chlorination
        
        Filtration
        
        Uses fresh water and let it pass through filter beds to remove insoluble solids e,g, pebbles, soil
        
        Chlorine
        
        The water is sterilized by using the chlorine to kill the microbes or pathogens
        
        Water is essential for life, so microbes and pathogens must be kill for safe consumption
  - - - Blue anhydrous Cobalt (II) Chlorine Turns pink in water
    - - White anhydrous Copper (II) Sulfate turns blue in water
  - - - Drinking water
      - Cleaning
    - - As coolant
      - As solvent
- - - - 21% Oxygen
      - Rest is noble gases and carbon dioxide
      - 78% Nitrogen
    - - Nitrogen has a lower boiling point than oxygen
      - -200 Celsius: Air is liquefied
      - -196 Celsius: Temperature is raise to let Nitrogen change stage into gas
      - Nitrogen is collected and removed
      - -183 Celsius: Oxygen turns into gas and remove
  - - - Effects
        
        Poisonous gas, binds with hemoglobin which reduces oxygen being delivered around the body
        
        Could lead to death as a result of carbon monoxide poisoning
      - Sources: incomplete combustion of carbon-containing
        substances
    - - Effects
        
        Forms acid rain
        
        Corrodes Buildings/ structures
        
        Kills plants and aquatic life
      - Sources: Combustion of fossil fuels that contain sulfur
        compounds
    - - Effects
        
        Reacts with other pollutants under the sunlight to form photo chemical smogs which causes breathing diffficulities
      - Sources: Car engines
    - - Sources: Leaded Petrol
      - Effects
        
        Lead poisoning, causes health issues
