d) Socio-economic environment
Answer: b) Water
Explanation: Water bodies are directly impacted by oil spills and chemical runoff, leading to water pollution, harm to aquatic life, and risks to human health through contaminated drinking water.
3. Excessive levels of traffic and construction activities predominantly affect which environmental factor?
a) Air
b) Water
c) Noise
d) Socio-economic environment
Answer: c) Noise
Explanation: Noise pollution is mainly caused by transportation and construction activities, leading to various health issues such as hearing impairment and sleep disturbances.
4. Deforestation and urbanization primarily impact which aspect of the environment?
a) Air
b) Water
c) Noise
d) Socio-economic environment
Answer: d) Socio-economic environment
Explanation: Deforestation and urbanization can lead to socio-economic impacts such as loss of biodiversity, displacement of communities, and changes in local economies.
5. Acid rain is a consequence of pollution primarily affecting which environmental component?
a) Air
b) Water
c) Noise
d) Socio-economic environment
Answer: a) Air
Explanation: Acid rain is formed when pollutants in the air, such as sulfur dioxide and nitrogen oxides, react with water vapor, creating acidic precipitation that can harm ecosystems and infrastructure.
6. Which environmental factor is most directly linked to the concept of habitat destruction?
a) Air
b) Water
c) Noise
d) Socio-economic environment
Answer: b) Water
Explanation: Habitat destruction often occurs due to water pollution and alteration of aquatic ecosystems, leading to loss of biodiversity and ecological imbalance.

a) Air
b) Water
c) Noise
d) Socio-economic environment
Answer: d) Socio-economic environment
Explanation: The socio-economic environment encompasses factors such as resource distribution, access to clean water, and the economic implications of environmental policies and practices.
8. Which environmental factor is most closely associated with the phenomenon of greenhouse gas emissions?
a) Air
b) Water
c) Noise
d) Socio-economic environment
Answer: a) Air
Explanation: Greenhouse gases, such as carbon dioxide and methane, contribute to global warming by trapping heat in the Earth’s atmosphere, primarily affecting the air environment.
9. Pollution from industrial discharge and agricultural runoff mainly impacts which aspect of the environment?
a) Air
b) Water
c) Noise
d) Socio-economic environment
Answer: b) Water
Explanation: Industrial discharge and agricultural runoff introduce pollutants into water bodies, causing water pollution and affecting aquatic ecosystems and human health.
10. Deforestation and loss of biodiversity are significant concerns primarily associated with which environmental factor?
a) Air
b) Water
c) Noise
d) Socio-economic environment
Answer: a) Air
Explanation: Deforestation contributes to air pollution by reducing the capacity of forests to absorb carbon dioxide, while loss of biodiversity affects ecosystem services that maintain air quality and climate regulation.
