Pollutants
What is one source of nitrogen as a pollutant?
What carbon compound is one of the 3 greenhouse gases?
carbon dioxide
Name 2 greenhouse gases
Methane, cabon dioxide, natural gas
Name 2 types of renewable energy
Hydroelectricity, solar, wind, tidal, geothermal, biofuel/biomass.

...Never gonna let you down.
Algae blooms - more grow, lowers oxygen concentration.
Hurts fish.
Why has more carbon dioxide entered the atmosphere in recent years?
What is the main difference between renewable energy and fossil fuels?
Fossil fuels are finite, or fossil fuels release lots of carbon dioxide.
Why might it be a good idea to set up multiple types of renewable energy in the same place - why don't we just do heaps of one type?
Because they're inconsistent - most require a certain type of weather so we want to cover all the bases (sunny days, windy days, rainy days)

...'In the shape of an L on her forehead.'
What is an example of a heavy metal?
Lead, arsenic, mercury.
Ocean acidification occurs. This harms sea life, especially shellfish as their shells are broken down.
How do greenhouse gases affect the atmosphere?
Accumulate, reflecting light from the Earth back to the Earth rather than into space --> heating up.
Explain the mechanism of 1 type of renewable energy
(explain how one works)
'You know you love me, I know you care'...
...'Just shout whenever, and I'll be there'.
Why are air particulates bad for us?
Get into our lungs and cause infection when they build up.
Where is carbon stored? Give some examples.
Fossil fuels - underground. Natural gas, oil, coal.
How do carbon dioxide levels affect water vapour levels?
They increase - because carbon dioxide warms up the planet, water evaporates.
What energy transformation takes place in wind energy/wind turbines?
Kinetic --> electric

...'There's vomit on his sweater already, mom's spaghetti.'
How could we reduce the effect of sediment?
Plants trees - excess sediment is caused by deforestation.
What chemical reaction produces carbon dioxide?
Combustion of a fuel
'Climate change is the climate getting hotter'
What is the more scientific, correct, definition of climate chage?
Climate change is the overall increase in temperature over time and more unpredictable weather events
What energy transformation occurs in the process of getting hydroelectric power?
Gravitational potential --> kinetic --> electric
