Quiz 7 Flashcards
Give 2 reasons why public understanding of climate change is often poor
Complex modes require simplification
Media reports can be biased
Particulates are an atmospheric pollutant. Explain their source
Incomplete combustion of a fuel
Releases solid particles and unburned hydrocarbons
And forms particulates in the atmosphere
Explain how greenhouse gases increase the earths average temperature
Short wave radiation is transmitted from the sun through the atmosphere
It is absorbed and re-radiated as long wave radiation
It is absorbed by greenhouses gases in the atmosphere
Name the process that describes the increasing average temperature of the earth
Global warming
State the effect of sulfur dioxide as an atmospheric pollutant
Acid rain and respiratory problems
Name the 4 potential effects of climate change
Ice caps melting
Sea levels rising
Extreme weather events
Habitat loss
Flooding
Name the process that global warming can lead to
Climate change
State a negative environmental effect of acid rain
Damages trees,reacts with sedimentary rock and harms aquatic life
Sulfur dioxide is an atmospheric pollutant. Explain its source
Sulfur impurities in combusted fossil fuels
Nitrogen oxides are atmospheric pollutants. Explain their source
Atmospheric nitrogen and oxygen react in the high temperature conditions of combustion
Name the 3 greenhouse gases
Water vapour, carbon dioxide and methane
State the name given to the total amount of carbon dioxide and other greenhouse gases emitted over the full lifecycle of a product,service or event
Carbon footprint
Name 2 human activities which increase carbon dioxide levels in the atmosphere
Deforestation and burning fossil fuels
Name 2 human activities which increase methane levels in the atmosphere
Cattle farming and rice farming
Carbon monoxide is an atmospheric pollutant. Explain its source
Incomplete combustion of a fuel
State the approximate proportion of oxygen in the earths current atmosphere
0.2
State the effects of nitrogen oxides as an atmospheric pollutant
Acid rain and respiratory problems
Which gases are present in small proportions in the earths current atmosphere?
Carbon dioxide,water vapour and noble gases
State the approximate proportion of nitrogen in the earths current atmosphere
0.8
State the effect of particulates as an atmospheric pollutant
Global dimming and health problems
Explain the effect of carbon monoxide as an atmospheric pollutant
It’s toxic,but colourless and odourless so difficult to detect
