41
Which gas is primarily responsible for global warming and is monitored in environmental geology?
Discuss
Answer & Solution
Answer: Option C
Solution:
Carbon dioxide (CO?) is the major greenhouse gas emitted by human activities.It traps heat in the atmosphere causing global warming.
42
What is bioremediation in environmental geology?
Discuss
Answer & Solution
Answer: Option B
Solution:
Bioremediation uses living organisms like bacteria and plants to degrade or absorb pollutants.It is a sustainable and eco-friendly cleanup method.
43
What factor primarily influences the rate of soil erosion?
Discuss
Answer & Solution
Answer: Option B
Solution:
Vegetation cover protects soil from rainfall impact and wind.Loss of vegetation increases erosion drastically.
44
Which of the following is a primary goal of sustainable mining practices?
Discuss
Answer & Solution
Answer: Option B
Solution:
Sustainable mining aims to reduce environmental damage, conserve resources, and protect ecosystems.It balances economic and environmental concerns.
45
What does the term �environmental impact assessment (EIA)� mean?
Discuss
Answer & Solution
Answer: Option B
Solution:
EIA is a systematic process to predict environmental consequences before project approval.This helps in planning mitigation measures to reduce harm.
46
Which of the following is NOT considered a renewable resource?
Discuss
Answer & Solution
Answer: Option D
Solution:
Coal is a fossil fuel and thus non-renewable.Wind, solar, and groundwater are renewable when managed properly.
47
What type of soil pollution is caused by excessive use of chemical fertilizers?
Discuss
Answer & Solution
Answer: Option B
Solution:
Nutrient pollution from fertilizers leads to eutrophication in water bodies.This disrupts aquatic ecosystems and water quality.
48
Which geological feature acts as a natural barrier to groundwater flow?
Discuss
Answer & Solution
Answer: Option C
Solution:
Aquiclude is a geological formation with very low permeability.It blocks or greatly slows groundwater movement.
49
Which of these is a major consequence of deforestation related to geology?
Discuss
Answer & Solution
Answer: Option B
Solution:
Deforestation removes tree roots that stabilize soil.This leads to increased erosion and slope failures.
50
What is the purpose of environmental monitoring in geological engineering?
Discuss
Answer & Solution
Answer: Option B
Solution:
Environmental monitoring tracks pollution levels, habitat changes, and geological risks.It supports informed decision-making and regulatory compliance.
