-
Air pollution
-
Soil contamination
-
All of the above
D
Correct answer
Explanation
Foliar fertilization can contribute to eutrophication of water bodies, air pollution, and soil contamination.
Which of the following is not a potential environmental impact of foliar fertilization?
-
Eutrophication of water bodies
-
Air pollution
-
Climate change
-
Soil contamination
C
Correct answer
Explanation
Climate change is not a direct environmental impact of foliar fertilization.
What is the primary cause of pollution?
-
Natural processes
-
Human activities
-
Both natural processes and human activities
-
None of the above
C
Correct answer
Explanation
Pollution can be caused by both natural processes, such as volcanic eruptions and forest fires, and human activities, such as industrial emissions and deforestation.
Which of the following is an example of a positive externality caused by pollution?
-
Increased property values
-
Improved air quality
-
Reduced healthcare costs
-
Increased respiratory illnesses
A
Correct answer
Explanation
In some cases, pollution can lead to positive externalities, such as increased property values near industrial areas due to the availability of jobs.
Which of the following is not a consequence of over-extraction of groundwater?
-
Land subsidence
-
Saltwater intrusion
-
Increased water quality
-
Depletion of aquifers
C
Correct answer
Explanation
Over-extraction of groundwater can lead to land subsidence, saltwater intrusion, and depletion of aquifers. It does not improve water quality.
Which of the following is not a consequence of water pollution?
-
Eutrophication
-
Habitat destruction
-
Increased biodiversity
-
Health problems
C
Correct answer
Explanation
Water pollution leads to eutrophication, habitat destruction, and health problems. It does not increase biodiversity.
