Stratosphere
Troposphere
The correct percentage of Nitrogen in our atmosphere is
21%

The ozone layer protects life on earth from
infrared wavelengths
ultraviolet wavelengths
microwaves
gamma radiation
Which of the following gases does not contribute to the greenhouse effect.
methane (CH4)
CFCs
nitrous oxides (NOx)
ozone
Which of the following is NOT a result of depletion of the ozone layer?
Increase in rates of skin cancer
Lower crop harvests
Dissruption of marine food chains
Increase of carbon dioxide levels in the atmosphere.
The main impact of tropospheric ozone is that
it absorbs ultraviolet radiation
it causes respiratory problems in mammals
it increases the rate of photosynthesis
it causes global warming
In which layer of the atmosphere does the earth's weather occur?
Thermosphere
Stratosphere
Mesosphere
Troposphere
Which of these are effects of ultraviolet radiation?
Damage to cells responsible for photosynthesis.
All of these
Genetic mutations
Weakening of the immune system
Which component of the atmosphere often plays an important role in ensuring the functioning of the albedo effect?
Nitrogen
Clouds
Ozone
Oxygen
Some gases in the atmosphere, such as water vapour and carbon dioxide, are known to trap the infrared light (IR) of longer wavelengths, thus warming up the planet Earth. What is this phenomenon called?
Greenhouse effect
Global dimming
Global climate change
Human enhanced green house effect
Which of the following medical conditions threatens humans exposed to photochemical smog?
Physical mutations
Leprosy
Asthma
Malaria
The main primary pollutants that contribute to the formation of acid deposition are:
Sulphur monoxide and nitrogen monoxide
Sulphur oxides and nitrogen dioxide
Sulphur dioxide and nitrogen dioxide
Sulphur dioxide and nitrogen oxides
The composition of the atmosphere may change dynamically over time. What is the effect on the rates of photosynthesis if the concentration of carbon dioxide in the atmosphere increases?
Rates increase
It's hard to predict
Rates remain the same
Rates decrease
Nitrogen leaving the atmosphere either through nitrogen-fixing or lightning is an example of an atmospheric:
Output
None of the answer alternatives
Input
System
By burning fossil fuels, humans produce additional amounts of carbon dioxide which enters the Earth’s atmosphere. CO2 from this source is therefore an example of an atmospheric:
Input
Transformation
Output
Transfer
Which part of the atmosphere is where most weather is found?
Stratosphere
Weather is found in all layers of the atmosphere.
Ozonosphere
Troposhpere
Towns and cities placed in valleys where mountains or hills prevent the wind from driving the photochemical smog away are called:
Thermal retroversion traps
Thermal subversion traps
Thermal conversion traps
Thermal Inversion traps
What is the difference between primary and secondary pollutants?
Primary pollutants are formed from a mixture of different secondary pollutants.
Primary pollutants have a more complex chemical structure than secondary pollutants.
There is no difference between primary and secondary pollutants.
Primary pollutants are emitted directly from a source, while secondary pollutants are created as a result of a set of reactions of primary pollutants.
