Start Quiz
1.
Which gas is mainly responsible for acid rain?
Carbon monoxide
Sulfur dioxide
Methane
Oxygen
2.
Which activity releases large amounts of methane?
Cattle farming
Burning coal
Photosynthesis
Planting trees
3.
In eutrophication, fish die mainly because:
Algae are poisonous
The water is too warm
Nitrates are toxic
Bacteria use up dissolved oxygen
4.
Carbon monoxide is dangerous because it:
Causes acid rain
Destroys ozone
Combines with haemoglobin
Is a greenhouse gas only
5.
Which is NOT a consequence of deforestation?
Soil erosion
Increased biodiversity
Increased atmospheric CO2
Leaching of nutrients
6.
Greenhouse gases warm the Earth by:
Absorbing infrared radiation re-emitted from Earth
Reflecting sunlight away
Destroying the ozone layer
Absorbing all visible light
7.
Which statement best describes Biochemical oxygen demand?
The release of harmful substances or energy into the environment by human activity.
A measure of how much oxygen microorganisms use in water; high values indicate organic pollution.
The washing of soluble nutrients such as nitrates out of soil by rain.
Rain with low pH caused by sulfur dioxide and nitrogen oxides dissolving in water in the atmosphere.
8.
Which statement best describes Enhanced greenhouse effect?
The release of harmful substances or energy into the environment by human activity.
The extra warming of the Earth caused by increased levels of greenhouse gases from human activities.
Rain with low pH caused by sulfur dioxide and nitrogen oxides dissolving in water in the atmosphere.
The large-scale cutting down of forests.
9.
Which statement best describes Leaching?
The washing of soluble nutrients such as nitrates out of soil by rain.
A gas such as CO2, methane, water vapour, nitrous oxide or CFCs that absorbs and re-emits infrared radiation.
A toxic gas from incomplete combustion that binds to haemoglobin.
A measure of how much oxygen microorganisms use in water; high values indicate organic pollution.
10.
Which statement best describes Deforestation?
A toxic gas from incomplete combustion that binds to haemoglobin.
The extra warming of the Earth caused by increased levels of greenhouse gases from human activities.
Excess nutrients in water causing algal growth, decomposition and oxygen depletion, killing aquatic organisms.
The large-scale cutting down of forests.
