Pollution and Human Impact Questions
Which type of marine pollution is caused by the introduction of non-native species into marine ecosystems, often through ballast water discharge from ships?
-
Oil Spills
-
Plastic Pollution
-
Eutrophication
-
Invasive Species
D
Correct answer
Explanation
Invasive species pollution refers to the introduction of non-native species into marine ecosystems, often through ballast water discharge from ships, which can disrupt native ecosystems and cause ecological imbalances.
What is the primary source of radioactive pollution in the oceans?
-
Nuclear Power Plants
-
Medical Waste
-
Industrial Waste
-
Atmospheric Deposition
A
Correct answer
Explanation
Nuclear power plants are the primary source of radioactive pollution in the oceans, as they release radioactive isotopes into the environment through cooling water discharge and accidental releases.
What are some of the environmental concerns associated with mining?
-
Air pollution from dust and emissions.
-
Water pollution from runoff and leaching.
-
Land degradation and deforestation.
-
Loss of biodiversity.
-
All of the above.
E
Correct answer
Explanation
Mining can have a number of negative environmental impacts, including air pollution from dust and emissions, water pollution from runoff and leaching, land degradation and deforestation, and loss of biodiversity.
Which of the following is not a type of soil pollution?
-
Pesticides
-
Herbicides
-
Fertilizers
-
Heavy metals
C
Correct answer
Explanation
Fertilizers are not a type of soil pollution because they are used to improve soil fertility and plant growth.
Which of the following is NOT a potential environmental impact associated with the utilization of renewable resources?
-
Habitat destruction
-
Water pollution
-
Reduced greenhouse gas emissions
-
Air pollution
C
Correct answer
Explanation
Renewable resources, by their nature, are associated with reduced greenhouse gas emissions compared to non-renewable resources. The other options, such as habitat destruction, water pollution, and air pollution, are potential environmental impacts that can arise from the development and utilization of renewable energy sources.
Which of the following is NOT a type of environmental externality?
-
Air pollution
-
Water pollution
-
Climate change
-
Traffic congestion
D
Correct answer
Explanation
Traffic congestion is a type of economic externality, but it is not an environmental externality.
What is the primary source of water pollution in developing countries?
-
Industrial waste
-
Agricultural runoff
-
Sewage discharge
-
Oil spills
C
Correct answer
Explanation
In developing countries, sewage discharge is the primary source of water pollution due to inadequate sanitation infrastructure and lack of wastewater treatment facilities.
How can we address the social impacts of water pollution?
-
Invest in water infrastructure and sanitation
-
Promote water conservation and efficiency
-
Implement stricter regulations on water pollution
-
All of the above
D
Correct answer
Explanation
Addressing the social impacts of water pollution requires a comprehensive approach that includes investments in water infrastructure and sanitation, promoting water conservation and efficiency, implementing stricter regulations on water pollution, and empowering communities to participate in water management decisions.
Which technology is commonly employed for noise pollution monitoring?
-
Sound level meters
-
Noise dosimeters
-
Acoustic cameras
-
Vibration monitors
A
Correct answer
Explanation
Sound level meters are commonly used for noise pollution monitoring. They measure the sound pressure level and provide information about the intensity and frequency of noise.
Which of the following is NOT a type of coastal and marine pollution?
-
Oil spills
-
Plastic pollution
-
Fertilizer runoff
-
Deforestation
D
Correct answer
Explanation
Deforestation is not a type of coastal and marine pollution, but rather an environmental issue related to the clearing of forests.
What is the primary source of plastic pollution in oceans?
-
Industrial Waste
-
Agricultural Runoff
-
Shipping Activities
-
Land-based Litter
D
Correct answer
Explanation
Land-based litter, such as plastic bags, bottles, and straws, is the primary source of plastic pollution in oceans.
What are the primary impacts of ocean pollution on marine life?
-
Habitat Destruction
-
Ingestion of Plastic
-
Entanglement
-
All of the above
D
Correct answer
Explanation
Ocean pollution can cause habitat destruction, ingestion of plastic by marine animals, entanglement in plastic debris, and other negative impacts on marine life.
What is the main focus of environmental geography research in India?
-
Climate change and its impacts

Which environmental change is primarily caused by the accumulation of salt in soil or water, often resulting from irrigation practices or natural processes?
-
Salinization
-
Desertification
-
Acidification
-
Eutrophication
A
Correct answer
Explanation
Salinization is the process by which soil or water becomes increasingly salty, often due to irrigation practices or natural processes like seawater intrusion.
