Human Impact (Water Pollution (Types of Pollution (What are they? (Toxic…

- - - - Toxic Pollution- is the presence of pesticides, oil, industrial waste, household chemicals, mining waste, lead, and radioactive nuclear waste in the water.
        
        Sediment Pollution- it is the presence of excessive silt and clay in water.
        
        Nutrient Pollution- is the presence of excess nitrogen and phosphorus in the water.
        
        Bacterial Pollution- it is the presence of harmful bacteria in water supplies.
- - - - Ex- Incandescent lamp A type of light in which an electrical current passes through a thin tungsten filament, causing it to glow and give off light.
        
        Ex- Fluorescent lamp a light source that consists of a glass tube coated with phosphor and filled with argon and another inert gas
        
        Ex- Halogen lamp a type of lamp in which the tungsten filament is encased
        in a capsule containing a mixture of gases that allow it to operate at a high temperature.
    - - Examples-Computers, Air Conditioner, Electric Stoves, and the Water Heaters are all examples of electrical household appliances
    - - Current- (I) is a measure of the amount of electrical charge that passes through the circuit each second.
        
        Wattage- (W) is the measure that is used by a device each second.
        
        Energy Consumption (usage)- is the total amount of energy used in a given time period. It is measured in kilowatt-hours (kWh)
        
        Lumen- a measure of the light produced by a lamp.
        
        Units of wattage- include
        the watt (W) and kilowatt (kW)
        
        AxV=W for voltage and wattage
- - - - Greenhouse Gases- a gas in Earth's atmosphere that absorbs and then re-radiates heat.
        
        Types of Greenhouse gases
        
        Methane
        
        Nitrous Oxide
        
        Carbon Dioxide
        
        The heat from the sun that gets trapped is used to warm our earth.
        
        Without the greenhouse gas there wouldn't be as much heat

        Biosphere
        
        Geosphere
        
        Hydrosphere
        
        Atmosphere
        
        Lithosphere
      - Carbon reservoir- a part of Earth that stores carbon.
        
        Carbon sink- a carbon reservoir that absorbs carbon from the atmosphere and stores it for a long period of time.
        
        Fossil fuel- a fuel that has formed over thousands or millions of years from the remains of living organisms.
        
        Decomposer- an organism that absorbs nutrients from living things or the organic matter they leave behind, turning it into simpler inorganic matter.
