11
What is the best method to monitor groundwater contamination?
Discuss
Answer & Solution
Answer: Option C
Solution:
Borehole sampling allows direct access to groundwater for chemical analysis, making it the most accurate method for detecting contamination levels and spread.
12
Which of the following contributes significantly to land subsidence?
Discuss
Answer & Solution
Answer: Option C
Solution:
Over-extraction of groundwater causes compaction of aquifer systems, leading to vertical ground settlement or land subsidence.
13
What is the major source of arsenic contamination in groundwater?
Discuss
Answer & Solution
Answer: Option C
Solution:
Natural leaching from arsenic-bearing rocks into aquifers is the dominant cause of arsenic pollution in many regions, especially in alluvial plains.
14
Why are wetlands important in environmental geology?
Discuss
Answer & Solution
Answer: Option C
Solution:
Wetlands filter pollutants, recharge groundwater, and provide flood protection, making them vital for ecological and hydrological stability.
15
Which of the following is considered a sustainable method for erosion control?
Discuss
Answer & Solution
Answer: Option C
Solution:
Vegetative cover stabilizes soil with root systems, reduces runoff velocity, and is an environmentally sustainable erosion control method.
16
What is the purpose of an Environmental Impact Assessment (EIA)?
Discuss
Answer & Solution
Answer: Option C
Solution:
An Environmental Impact Assessment (EIA) is a study to evaluate potential environmental risks of a proposed project, aiming to reduce negative consequences.
17
Which rock type is most vulnerable to acid rain effects?
Discuss
Answer & Solution
Answer: Option D
Solution:
Limestone (composed of calcium carbonate) reacts with acidic water, causing surface deterioration and material loss, making it highly susceptible.
18
How does climate change affect geohazards?
Discuss
Answer & Solution
Answer: Option C
Solution:
Climate change amplifies geohazards like floods, landslides, and coastal erosion due to changing precipitation patterns, sea level rise, and temperature shifts.
19
Which type of pollution is most associated with abandoned mines?
Discuss
Answer & Solution
Answer: Option C
Solution:
Heavy metal contamination from acid mine drainage pollutes nearby soil and water, posing long-term ecological and health risks.
20
What does the term "carbon footprint" represent?
Discuss
Answer & Solution
Answer: Option B
Solution:
A carbon footprint is the total greenhouse gas emissions, expressed in CO? equivalents, produced directly or indirectly by a person, organization, or product.
