7.
Limited levels of carbon dioxide and methane are recommended to be in the atmosphere to retain heat.
a)
True
b)
False
8.
The greenhouse effect is beneficial as it helps to sustain life on earth by naturally trapping heat in the atmosphere.
a)
False
b)
True
9.
The enhanced greenhouse effect is the increase in global temperatures due to an increase in atmospheric greenhouse gases.
a)
True
b)
False
10.
What is another term for enhanced greenhouse effect?
a)
Global cooling
b)
Global freezing
c)
Global barbecue
d)
Global warming
11.
The more sunspots there are, the greater the amount of solar radiation emitted by the sun, resulting in global cooling.
a)
False
b)
True
12.
Natural variations in solar output can result in variations in global temperature (global warming and global cooling) over the course of 11 years.
a)
True
b)
False
13.
During volcanic eruptions, large volumes of sulfur dioxide released into the atmosphere can work together with dust and ash to cause global cooling.
a)
True
b)
False
14.
During volcanic eruptions, large volumes of carbon dioxide can be ejected into the atmosphere to bring about global warming.
a)
Not true.
b)
True.
15.
By cutting down our demand for meat derived from cattle, we can actually contribute to less greenhouse gas emissions in terms of ____________.
a)
Carbon dioxide
b)
Nitrous oxide
c)
Methane
d)
Water vapour
16.
Agricultural activities can lead to more greenhouse gas emissions through _____________.
a)
Cattle belching
b)
Usage of tractors powered by fossil fuels
c)
Usage of organic fertilisers
d)
All of the above.
17.
How can deforestation NOT lead to an increase in atmospheric carbon dioxide and climate change as a result?
a)
Setting forest fires to clear forests rapidly for agricultural activities release carbon dioxide due to combustion.
b)
The loss of forests as a carbon sink i.e. forests absorb carbon dioxide during photosynthesis.
c)
The loss of oxygen which makes the earth warmer, as forests contribute oxygen to the atmosphere during photosynthesis.
d)
Carbon oxidation whereby carbon in exposed soil (without vegetation cover) reacts with oxygen to produce carbon dioxide.
18.
The burning of fossil fuels (eg. coal, gas, and oil results in the release of __________.
a)
Oxygen
b)
Methane
c)
Carbon dioxide
d)
Nitrogen
19.
When there is urbanisation, there is an increase in greenhouse gas emissions due to all of the following, except for ____________.
a)
Urban dwellers requiring higher energy consumption for household activities (eg. heating, lighting, cooling, cooking).
b)
Urban dwellers using public transport instead of private transport.
c)
More ownership of cars and usage of other motor vehicles in urban areas, which are powered by burning of fossil fuels.
d)
More industrial activities (eg. manufacturing and construction) in urban areas which lead to more fossil fuels burnt for energy consumption.
